Introduction: A DIY AFM Whokshop

There is an DIY AFM workshop with one hobbyist from the States and one professor from India. They assembled their own DIY AFM within 2 hours crafting time.

Here is a link to previous project:

https://www.instructables.com/id/A-Low-Cost-Atomic-Force-Microscope-%E4%BD%8E%E6%88%90%E6%9C%AC%E5%8E%9F%E5%AD%90%E5%8A%9B%E9%A1%AF%E5%BE%AE%E9%8F%A1/

Step 1: Preparing the Parts Before Assembly......

Finish edges of the parts.

Step 2: This Time...we Use Instant Glue....

In stead of solder, all the structures are glued by instant glue, which makes assembly easier and healthier.

Step 3: Wiring the Scanner....

Use solder iron for wiring cables of the scanner.

Step 4: Gluing the Z Axis Transducer of the Scanner

Very important!

Step 5: Assembling the AFM Head

Again....glue everything.....

Step 6: ​The Optical and Mechanical Parts Are Done!

Just put one magnet on top of the Z transducer.

Step 7: Performance Evaluation

The optomechanical part is connected to a AFM controller

Step 8: Low Cost AFM Calibration Sample: DVD Data Tracks

Use the DVD data tracks (pitch= 740 nm) for calibrating scanning range of the scanner.

Step 9: Measuring the AFM Calibration Sample (NT MDT TGQ1)

The DIY AFM with economy AFM controller can successfully measure height of square calibration features 20 nm with contact mode.

Step 10: Measuring 1.4 Nm Features on the TGQ1

Surprisingly we found that the DIY AFM can work with non-contact mode (attractive interaction between atoms caused by van-der-Waals forces) which resolves 1.4 nm height feature on the TGQ1.

http://en.wikipedia.org/wiki/Non-contact_atomic_force_microscopy

Step 11: The DIY AFM With Advanced Controller

The DIY AFM with advanced AFM controller can clearly see the DVD data tracks when operated in AC (Tapping) mode.

Step 12: The DIY AFM With Advanced Controller

20 nm Squares and 1.4 nm features are clearly seen.

Step 13: Measuring Nano Particles

Step 14: Resolution Limit Test....

The DIY AFM system with 12bits controller can resolve 0.5 nm which is similar to height of 2 carbon atom layers on HOPG (Highly Ordered Pyrolytic Graphite) surface.

Dear Professor Hwu,

I like this project very much, i'm studying a telecommunication degree and i'm thinking about doing something similar as final degree project but I dont know if this project will exceed my project time. Could you send me the the detail instruction about how to make it?.

Thank you very much in advance and please keep posting interesting projects.

Dear Professor Hwu,

I like this project very much. I'm currently working on redesigning of AFM, which was made in 2004 at our institute. Could you send me the detail instruction on how to make it, it would be easy for me.

Thanks in advance!

Dear Professor Hwu,

I find your project very interesting. I'm currently building a low cost DC sputtering machine from microwave oven spare parts. If I manage to get it work, it would be wonderful if could measure the deposited thin layers at home. If it is possible, I'd like to ask you to send me a detailed instruction about your AFM solution (components, assembly, software descriptions).

Thank you for your help in advance and wish you success for your future work.

I'm working with a coatings start-up (3 people) and we need a very low cost AFM to look at our polymer coatings on nano-particles. Is it possible to share the other parts of this project - the DVD head + PZ driver schematics + software links? This is a GREAT project. I'd be happy to build an extra one and donate it to our local high school. john@jstockton.com
