Magnetic Force Microscopy – Description, Specifications And More

This NanoLithography software option enables the AFM probe to alter the physical or chemical properties of the surface. Created in LabVIEW and integrated with the AFMControl software. VI’s are available to customers who want to modify the software and create new capabilities.

Description
Model: LITHO

This Lithography Software Option is used for nanolithography. That is, the AFM’s probe is used to alter the physical or chemical properties of the surface.

The software uses a script of commands to move the probe in a pre-determined pattern over a surface. The two commands are: “movement” and “hold”. During a movement and hold command, the voltage and force on the probe can be varied.A MOVEMENT command consists of 5 numbers (no letters) separated by commas:

They represent X, Y, Velocity, Setpoint%, and Z_DAC voltage
 X and Y are the coordinates in micron from the image plot.
 Velocity is the speed from one point to the next listed point in nm/sec.
 Setpoint% is the percent value of the existing setpoint.
 Z_DAC voltage is a voltage in the range of 0 to +5V which may be applied to the probe.

A HOLD command consists of 3 numbers (no letters) separated by commas:

They represent Setpoint%, Z_DAC voltage, and Delay Time (ms)

 Setpoint% is the percent value of the existing setpoint.
 Z_DAC voltage is a voltage in the range of 0 to +5V which may be applied to the probe.
 Delay time(ms) is the time in milliseconds that the probe is held in its present position.

A scripting file is a text file that may be created with any program capable of outputting a .txt file. Each motion of the probe required to create the pattern must be added to the .txt file. Complex patterns may be created using a large number of movement and hold commands.
As with all AFMWorkshop software products, this software option is created using VI’s in a LabVIEW™ environment and is integrated with the AFM Control software. The VI’s used to create the software are available to customers who want to modify the lithography software and create new capabilities.

Software

The lithography software window allows a user to load a scripting file. Once loaded, the pattern that will be made is displayed in an image window. When the start button is pressed, the script is implemented and the specifics of each step are listed in the window. A green light is displayed when the script is completed.

Education and Training With AFMWorkshop AFMs

Atomic Force Microscopes facilitate nanotechnology developments in all disciplines of science and engineering. There is an extensive and growing demand by students and professionals for AFM education and training.

Here are three types of students that AFMWorkshop products can be used for educating:

Exposure to the Nano World

Educators want to expose students to an atomic force microscope by showing them what an AFM looks like and how AFM operates. Most of the students learn that it is feasible to produce 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

Educators focused on training students to operate the AFM and to use the instrument for measuring images of several types of samples. Students are shown the basic Atomic Force Microscope operation, including how the feedback control works and how the instrument scans. This educational experience helps students that want to operate AFM instruments in industrial and research environments. This training can last from one week to an entire semester.

Career Options in AFM Design and Service

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