Introduction to the Atomic Force Microscope

The working principle of the Atomic Force Microscope (AFM) is based on the forces that arise when a sample surface is scanned with a nanometer-sized tip (a few to 10s of nm) attached to a cantilever.

The advancement of the AFM over traditional stylus surface profilers is that the former uses a feedback loop to control the forces between the surface and probe. Because the forces are controlled, very small probes may be used, and not broken while capturing an image.

AFMWorkshop products all include 5 standard modes. There are two primary modes used for measuring the topography of a sample, which are contact mode and vibrating mode. Lateral Force and Phase modes offer surface material contrast. Finally Force-Distance (F/D) curves measure the interaction forces between a probe and surface.

Contact Mode:

The probing tip is in contact with the surface throughout the imaging in contact mode. The short-range forces between the surface and tip cause the deflection of the cantilever, which is recorded to generate the topographical image of the surface. However, the tip-surface contact in this mode can potentially damage the surface or wear the tip. Hence, this mode may not be suitable for imaging of soft surfaces. On the other hand, continuous contact with the surface allows identifying other features such as friction (lateral force imaging) or stiffness/elasticity map of the surface (force modulation imaging).

Vibrating Mode:

In this mode, a probe at the end of a cantilever is vibrated up and down. As the vibrating probe begins to interact with a surface, the vibration amplitude is dampened. The amount of damping is proportional to the amount of force placed on the surface by the probe on each oscillation of the vibrating probe. A feedback loop is used to maintain a fixed vibration amplitude as the probe is scanned across a surface. Forces between the probe and surface in vibrating mode can be as low as a few 10’s of piconewtons.

Phase Imaging:

A phase difference between oscillation of the cantilever and of the signal that drives cantilever oscillation (for example, by a piezoelectric crystal) is measured and visualized in phase imaging.There is no phase contrast when the surface is homogenous, or when there is no interaction between the tip and surface (i.e., the cantilever is well above the surface). However, if specific regions of the surface have distinct mechanical properties, that can be captured with phase imaging. This is because the cantilever loses a different amount of energy as probe taps to surface areas with differing mechanical properties. Hence, phase imaging is helpful to detect variations in mechanical properties such as friction, adhesion, and viscoelasticity on surfaces. It can also be used to detect patterns of various materials such as polymers on the surface or to identify contaminants that cannot be distinguished with topography imaging.

Lateral Force Mode:

In lateral force or frictional force microscopy, lateral deflections of the cantilever, arising due to forces parallel to the plane of the sample surface such as friction force, are measured. This allows detecting inhomogeneities on the material which gives rise to variations in surface friction, or to measure the friction properties of a sample at the nanometer level.

Force-Distance Mode:

A force-distance curve is measured in contact mode. To measure an F/D curve the probe at the end of a cantilever is pushed into the surface of a sample. Once the probe begins to interact with the sample, the cantilever bends. The inbound part of a F/D curve is the deflection of the cantilever when the probe is being pushed into the sample, and the outbound corresponds to when the probe and sample are moving apart.

On-Site AFM Installation and Training Facilitates Optimal Installation and Function of Your New AFM

Atomic force microscopes can be purchased with an On-Site Training and Installation; AFMWorkshop will set up the AFM in your lab, and train users on the operation. Generally, two days long, On-Site AFM Installations and Training offer customers assurance that the AFM is placed in a proper vibration environment, and that all users are properly trained to operate the atomic force microscope.

For those AFMWorkshop customers electing On-Site Installation & Training on their AFM, vs. the Assembly and Training program at the AFMWorkshop facility, AFMWorkshop has designed a set of procedures to facilitate optimal installation and function of your new AFM.

Once the new AFMWorkshop AFM is received at your facility, an authorized AFMWorkshop customer service engineer travels to your facility to install the AFM and to train your AFM users on the particular model’s operative techniques.

AFMWorkshop’s on-site training is designed for up to two designated operators of the AFM. These operators are then designated as the primary contact points between AFMWorkshop and the customer’s institution. During the installation and training visit, the focus is on training customers how to make optimal images of standard samples, not on specific applications. We find that this approach yields the best results for future success with the AFM. (If your facility’s AFM operators are interested in continuing their training on specific applications, AFMWorkshop offers five-day advanced applications workshops throughout the year.)

Day 1

The objective is to set up the AFM and ensure it is operating to factory specifications. The AFM’s proposed location is reviewed and remedies to any potential negative ambient impacts on the AFM’s performance are discussed.

• Unpack AFM
• Set up AFM
• Evaluate AFM site for acoustic and structural vibrations
• Verify system specifications

Day 2

The objective is to train up to two operators on the skills required to operate the AFM and to make images of standard samples. Skills reviewed include:

• Changing samples
• Changing probes
• Aligning the light lever
• Positioning the photodetector
• Selecting resonance (vibrating mode only)
• Tip approach
• Scanning
• Optimizing GPID
• High resolution scanning on the AFMWorkshop product

The final component to the AFMWorkshop On-Site Installation and Training is the preparation of a service installation report, completed and signed by both the installation engineer and the customer at the end of Day 2. This report verifies that the instrument is properly functioning and/or makes note of any problems that may need further attention. After the installation, follow-up questions should be primarily directed to the AFMWorkshop service engineer who performed the installation, and come through one of your facility’s two designated AFM users receiving the training.

AFMWorkshop covers all travel costs as well as room and board for the customer service engineer. We request a minimum of two weeks advance notice to schedule the installation.

Here’s How Atomic Force Microscope Can Help Students Develop Their Skills

AFMs for Educators

Educators generally have one or more of the following three objectives in mind when designing their AFM Education and Training programs for better students learning. The types of AFMs needed – and the dollar amount budgeted for their purchase – vary depending upon which objective the educator wants to accomplish.

For Students

Atomic Force Microscopes are key nanoscale measurement instruments facilitating nanotechnology developments in all disciplines of science and engineering. There is a substantial and growing demand by students as well as professionals for AFM Education and training. AFMWorkshop has considerable advantages for both groups of learners.

Expose Students to the Nano World

Educators who fall within this category seek to expose students to an atomic force microscope by showing them what an AFM looks like and how it operates. Students learn that it is possible to create a magnified view of a surface with a scanning tip. Typically, a few samples are imaged during this exposure time so that students directly see the nanometer-sized features on a surface. In this group, students are generally exposed to the AFM for a few hours.

Train Students to Operate an AFM

This group of educators is focused on training students how to operate the AFM and how to use the instrument for measuring images of several types of samples. Students are exposed to the basic operation of the Atomic Force Microscope, including how the instrument scans and how the feedback control works. This educational experience prepares the student for operating AFM instruments in research and industrial environments. This training can last anywhere from one week to an entire semester.

Build Student Career Potential

Educators within this category seek to prepare students for a career in instrumentation design or instrument customer service. This is accomplished in part by helping students understand the design and construction of an Atomic Force Microscope. This group may include an additional category of researchers who intend to modify or repair their own instruments. Students will build their own AFMs and learn how to measure images on standard reference samples. A one week intensive 40-hour course can accomplish this group’s objective.

AFMWorkshop offers instrumentation and training materials to meet the demands of all three educational groups.

AFM Instrumentation

One of our most popular instruments used in educational settings is the TT-2 AFM. Because the TT-2 AFM is similar to 99% of the Atomic Force Microscopes used in research labs throughout the world, students can use skills developed on the TT-2 AFM to operate AFMs with more complex instrumentation.

On a TT-2 AFM, students learn how to operate all of the key modes such as contact, vibrating, lateral force, and phase modes. For example, the TT-2 AFM and AFMWorkshop were selected as instruments and trainers of choice by Hiroshi Yokoyama, Ph.D., director of Kent State University’s Glenn H. Brown Liquid Crystal Institute.
