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.
@@krishnavenkatesh8039 it makes it so much better to understand than if he had a thick Indian accent. Indian accent is only beautiful for Indian languages, not English.
