1. ### !Measuring Currents in a Circuit w/ Semiconductor

Sorry Dale and thank you robphy for drewing my attention. I've edited the title to a more reasonable one
2. ### !Measuring Currents in a Circuit w/ Semiconductor

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...
3. ### I What should be continuous at the interface of two materials?

Sure, but is it true also for metal/semiconductor interface?
4. ### I What should be continuous at the interface of two materials?

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...
5. ### I What should be continuous at the interface of two materials?

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
6. ### I What should be continuous at the interface of two materials?

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...
7. ### A Numerical solution for a two dimensional 3rd order nonlinear diff. eq.

I'm a bit lost in all the numerous methods for solving differential equations and I would be very grateful if someone could point me to some direction. I want to solve the following boundary conditioned differential equation: a_1+a_2\nabla f(x,y)+a_3\nabla f(x,y)\cdot \nabla^2...
8. ### Steady state boundary conditions between metal/dielectric?

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...
9. ### Steady state boundary conditions between metal/dielectric?

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...
10. ### Solve Laplace equation on rectangle domain

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
11. ### Solve Laplace equation on rectangle domain

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
12. ### Solve Laplace equation on rectangle domain

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...
