This is so interesting. Can't believe how far I am from state-of-the-art knowledge and technology. I wonder if I will ever be close to anything like this. I'm an Electromechanical Engineering student in Panama. Thanks for making this video!
It’s a great video thank you , it helped me understand how the technology works But I don’t get how it represents quantum tunneling. It doesn’t measure or calculate the probability of a wave tunneling through a barrier. They actively transfer electron as a particle between two surfaces and measure how current changes based on the difference between the distance between the sample surface and the tip
@@oskarilehto Late, but here for the curious. You know how electric/grill lighters work? The CLICK you hear is the smacking of a tiny hammer onto a quartz crystal. Quartz is weird because it generates a small current when deformed. This also works in reverse, however. So, by applying a voltage to a quartz pedestal, the sample can be moved relatively accurately on the nano-scale by deforming the whole pedestal ever so slightly.
SPM is a general technique "scanning probe" and just describes the method of acquiring the image. It can use the laser light AFM or some other feedback like current in STM.

I feel the same way. i wonder if you got any closer during this 1 year :D
@@kimia1377 generally you'll get that closer in grad school, I've got some friends who work with SEM, TEM and STM during their masters and PhD's
Good luck with your studies!
if only all youtube videos were this concise and straight to the point
Huge thanks for this video, and generally for making videos that let the average joe understand things like this.
great video with straight forward explanations, thank you!
Huge thanks, as a first year Nanoscience grad.
Thanks for the very straightforward explanation , it will be useful for my students
Please don't use background music.. it's irritating.. and thank you
Thank you so much for explaining so easily.
Perfect example 👌
Thankyou.... Good and simple explanation.

Thank You... 💜🙏
Thank you
Excellent explanation
Awesome
Please do video on Electrophoresis &Types...
Thanks a lot 👌🏻
So the tunnelling effect is like the activation energy for chemical reactions ?
Thanks for the explanation!
Does anyone happen to know how is it possible to build such a thing? How can we move the needle with such a precision?

@@TheWoifeeeeeee thanks! Do you happen to have an english explanation? I cant speak germany :/

pretty nice explanation man :D
love the vid (fyi slight mispronunciation of the word 'probability')
Danke schönen
Thats great
Probablity
Does SPM also uses laser and mirror to find the movement of probe
SPM is a general technique "scanning probe" and just describes the method of acquiring the image. It can use the laser light AFM or some other feedback like current in STM.

how does one even come up with this damn i feel even more dumb now
video is good but the background music is so annoying and loud that I couldn't finish watching

bhai yaar accent mat maar
lol yea. its so fake. Other than that, good explanation

It's kind of distracting.
Thank You
