AFM Principle- Basic Training

[@maskedmarvyl4774]

Thank you for the video. It would have been nice if you had explained what the attractive and repulsive forces are and how they operate.

[@medaphysicsrepository2639]

Good question did you ever get an answer?
I assume its the intermolecular forces of the molecules you are working with ?

[@AmitTiwari-wf1xj]

Repulsive force - due to column force and Pauli expulsion principle
Attractive force- Vander waal force

[@kamacite16]

Check the Lennard-Jones potential.

i just understood at once with this nice descriptions thanks

[@saralashanthi.j9258]

Excellent Session.

[@eashwararajusenthilkumar8638]

Describe how to measure friction with AFM and why it is important to calibrate the scanner?

[@VinayMishra-ux4qp]

In the non-contact mode /Tapping mode, when the tip doesnot touch the surface at all, so why not it just hovers above the surface with a attractive forces, (may be due to Tunneling electrons), why it needs the tapping in the first place?

[@Shumayal]

Non contact and tapping modes are different. Tapping involves occasional touching.

[@MonstroRex]

This was helpful, thanks!

[@aaronessilfie2588]

Thank you for this video

[@_aurum]

if non contact afm is better then why still use contact afm

[@TridTV]

Non-contact AFM reduces resolution

[@VinayMishra-ux4qp]

@0.20 , I suppose you wanted to to say long range attaractive forces?
isn't that correct?

[@ajahjamael_TWL]

Very helpful and simply done.

[@kalpanazutshi7306]

Thank you. That was very helpful. :)

[@sahilamin219]

how is this laser just pointing that tip so accurately that it shows every deflection ???
any guess plz ans :) thanx

Marvelous

Me having exam after 2hrs, but me who accidentally see this video🤣🤣🤣

[@physik802]

cute

[@Vespansis]

you just broke optics' law about the angle of reflection

[@igor8473]

Daora!
