Introduction: A DIY AFM Whokshop

Picture of 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....

Picture of 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....

Picture of 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

Picture of 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)

Picture of 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

Picture of 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.

Step 11: The DIY AFM With Advanced Controller

Picture of 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

Picture of 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....

Picture of 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 am so excited if it is possible to do it at home, would you please kindly to send me the references.

Thanks

Hello Professor Hwu,

Like many others here, I am in awe of the quality of this device! I have worked with Asylum Research AFM's and it gets very finicky. I would love to see learn more about the code and what clever money-saving tricks were involved. If you are able to, my email is waldojeffersss@gmail.com

Thank You!

Dear Professor Hwu,

I have attempted AFM construction in the past. Many approaches required at least one prohibitively expensive component, such as a 3D nanopositioner. Other methods, using a divided four quadrant piezoelectric actuator, achieved poor quality results.

Your approach promises to fill the gap. I was wondering if I can download a full instruction sheet, schematics and parts list from instructables?

If I upgrade to Instructables premium, will full schematics be available?

Alternately, I notice other users are requesting direct email of appropriate information. My email is provided below If Email is the preferred method of communication.

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.
