The cAFM facility was installed in Electrical engineering department as a Central Facility as per RIFC norms. The facility is open for all IIT Bombay internal users to meet their research necessities.

The AFM consists of a nanoscale tip mounted on a cantilever that scans over the sample interacting with its force fields. The resulting deflections of the cantilever is converted into a laser beam deflections and it is used to map topography and morphology of samples. Additionally it can measure electrical, magnetic and piezo-electric behaviour of the surface using suitable probes.

• Instrument : Atomic Force Microscopy
• Model : MFP3D Origin
• Company : Asylum/ Oxford Instruments
• System has capability for :
  • AFM : Contact and tapping (non-contact) mode topography imaging.
  • CAFM : It can simultaneously map the topography and conductance distribution of a sample.
  • EFM : A non-contact AFM technique to probe stored electrostatic charges
  • MFM : A sharp magnetized tip scans a magnetic sample; the tip-sample magnetic interactions are detected and used to reconstruct the magnetic structure of the sample surface.
  • PFM : It measures the mechanical response when an electrical voltage is applied to the sample surface with a conductive tip of an AFM

• The sample preparation is minimum
• It has a maximum Scan Area of 90 x 90 μm² and minimum scan area determined by tip radius, which is around 10 to 30nm. Maximum Scan Depth is 14μm and minimum can be a few nanometres.
• Good external noise Isolation.
• It can measure localized IV using standard and custom waveforms though nano scale conductive tips.
• High speed pulse measurement capability through tip is also added.

1. For what kind of measurements this facility is used?

   This facility is used to map topography and morphology of samples using contact as well as tapping mode. Additionally it can measure electrical, magnetic and                piezoelectric behaviour of the surface using suitable probes.

2. Is this facility useful for imaging wet samples?
    No. Only hard thin films and dry samples are allowed. Powdered samples can be scanned after drop casting them on a suitable substrate.

3. Who can use this facility?
IITB students and staffs (Internal) can use this facility. Also it is open for External users. However, charges may apply.

4. What is the procedure for submitting the request for this facility?
    You can submit the request for cAFM through Drona IRCC website. Once your PI approves your request, we will allot you the slot as early as possible.

5. What are the rules for getting authorized for using this facility?
    One student/ staff from each group can get authorized to use this facility independently. The whole training procedure will include five slots consisting of one demo        session, three hands on sessions, and a final authorization test.

6. What happens if one violates the rules of the facility?
    The person is barred from entering the facility for indefinite period of time.

7. What should be the approximate sample size required?
    Preferably samples size should be less than 2cm × 2cm. For CAFM measurements back contact or visible bottom contacts/ pads are required.
