Hi, I have a questions regarding semiconductor-metal junctions that has been left unresolved. I hope that you can offer me an explanation. I know that when a metal and n-doped semiconductor are in contact upward band bending occurs. This is because the Fermi levels in the two materials...

Well, I think I figured it out but if you have any insightful comments please go ahead! The reason is that the eigenstate of particles going through A is |A,+> and through B is |B,->. Now if both were known to be spin up then we couldn't know the eigenstate of a single electron traveling...

Hi everyone, I have a question concerning the double slit experiment that I would like clarified. According to a book I am reading if the electrons passing through slit A are of spin up and the electrons passing through B are of spin down then there will be no interference pattern (just the...

Doc Al, Thanks for your help. I was able to get the solution this morning. I won't spoil the rest of the details for anyone who wants to try it.

Homework Statement I've been working on this problem for several hours with no luck. Any help would be appreciated. (It's not homework) A thin rod of mass M and length L is hinged at the bottom, and almost balanced vertically. It starts to fall. Find the tangential component of the force...
