Sorry Dale and thank you robphy for drewing my attention. I've edited the title to a more reasonable one

If so, what will I measure in the Ampermeter, the zero total current or the value of the conduction current? I was thinking of the following example- a circuit consist of a current source, an Ampermeter, a switch, and a semiconductor. The semiconductor can have both conduction and displacement...

Sure, but is it true also for metal/semiconductor interface?

Thanks for the answer. I will look for the books you suggested. However, there is a problem with Maxwell's boundaries. If the electric potential was continuous, then the voltage drop on a diode for example was that of the source without any consideration of the built-in potential. Than obviously...

l'm trying to understand the physics behind the interfaces of to materials, especially between semiconductors and metal (or poor conductor) electrodes. Both at equilibrium and at applied voltage

At the interface between: 1) conductor/conductor 2) conductor/semiconductor (or dielectric) 3) semiconductor/semiconductor (or dielectric/dielectric) What quantity should be continuous? Is it the electrochemical potential, only the chemical potential or is it the electric potential? Since they...

So, in the case of steady-state, the boundary conditions are the same as in electrostatic? My issue with the tangent component arises when looking at a one-dimensional problem. In this case, I can only "work" with the normal component. A second issue is with the displacement (D)? If D is...

There are few thing I'm not sure of and be happy for clarifications. In general: at steady state, what are the electric-field,potential, and current boundary conditions between a conductor and a dielectric medium? more specific: a) When dealing with a perfect conductor there exist a surface...

I'm not sure how to solve it when I have one side with Dirichlet boundary and the other side with Neumann boundary. U ( x , 0 ) = 0 U y ( x , b ) = 0 or U ( x , 0 ) = 0 U y ( x , b ) = v

I know the variable separation method. But I'm not sure how to do it when in one side of the rectangle there is a Dirichlet boundary U(x,b)=const and in the other one I have Neumann boundary Uy(x,0)=0

Homework Statement I'm having issues with a Laplace problem. actually, I have two different boundary problems which I don't know how to solve analytically. I couldn't find anything on this situations and if anybody could point me in the right direction it would be fantastic. It's just Laplace's...
