Boundary conditions are defined by Maxwell's/Gauss equations, so why we use ohmic/schottky boundaries in metal/semiconductor interfaces instead?

Maxwell's/Gauss equations define the electric fields and current density at the interface of metal/dielectric. Since semiconductor is a dielectric material, I would expect that these boundaries...

Is the current equals sigma multiplied by the spatial derivative of the electrochemical energy (or fermi energy)?

I saw in a paper that the current in a metal is sigma (conductivity=e*mu*n) multiplied by dk/dx where k is the electrochemical energy (or fermi energy). It seems to me that it is some kind of a...

Is there charges inside a metal when there is a current flow?

In electrostatics, inside a metal there are no charges (electric field equals zero, thus one can find the potential using Laplace equation (together with the proper boundary conditions). Is it...

Is there band bending in metal organic interface?

What are the main differences between metal-inorganic and metal-organic interfaces? Is there a band bending or migs (metal induced gap states) in the metal-organic interface? And how the...

I cannot get a uniform layer of PCBM in a Chlorobenzene solution on a PEDOT:PSS layer by Spin-Coating

I need to fabricate organic solar cells. The organic materials I'm using are soluble in Chlorobenzene (PCBM, P3HT, PCDTBT, and etc.) I'm doing some tests in order to obtain uniform layers on top...

What are the currents (conduction and displacement) inside a disconnected capacitor if between plates there is a time dependent electric field source?

The general term of the current reads J_total=J_conduction+J_Displacement. Where in most cases J_C obeys Ohms law and J_D=epsilon dE/dt. Usually when a capacitor is disconnected from the electric...
