How can we create electron-puddle in the 2D-transition metal dichalcogenides?

In the intrinsic graphene on substrate like SiO2, electron-hole puddles appears due to the charge impurity below graphene. Roughly, we can visualize these electron-hole puddles as dynamic p-n...

How can the interface potential between two material can be measured experimentally?

Generally, when metal comes into contact with semiconductor, there would be forming schottky barrier at the interface. And at the interface, there exists a depletion region where there is no...

What is the relation between electron affinity and the number of layers of layered structure material?

For layered materials, we can reduce the bulk counterpart to a single layer (say two-dimensional), the band gap will become larger as reducing the number of layers. But I am not sure about the...

How do you perform differentiation for measured sets of data?

I want to fit the I-V curve of a diode using the diode equation. The I-V curve is presented in the form of ln(I) vs V. But I want to know the dV/d(ln(I)) vs I, in order to extract the barrier...
