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...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

No streamlines present in a small region inside a flow. This means exactly what?

No streamlines present means whether the flow is getting obstructed there and the velocity inside the region is zero? Or else, the fluid is trapped inside that region with a nonzero velocity?...
