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...

How does the temperature degrade the voltage output from metal/semiconductor contact solar cell?

I read some literature on solar cell, all of which state that the voltage output of schottky-type solar cell will be reduced with rising temperature. But what i have learned from literature in...

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...

How to calculate the band structure/ density of state of graphene on the metal substrate?

Current research findings have shown that the graphene and metal contact can be divided into two categories: physisorption and chemisorption. What interests to me is how to obtain the...
