Hi, What is the best solid state physics video course available online. So far the best one i have found is this one .. but it is just introduction to Solid State Physics

I got everything except V2d=(2*Pi/L)*2. What is L. It only make sense if L is a x -dimension of the material, but if so, the states in x and y direction are quantized as well, Just Lx and Ly are much larger that Lz. So z quantization is the most important.

Thanks very much for answer . I uploaded another (i hope) better picture. It is a AlGaAs-GaAs-AlGaAs hetero-structure. So K-z is quantified in this case, K-x and K-y have continual values. So the electron is free to move along x-axis and y-axis (using conduction level), but when he...

It is a classic 2DE quantum well problem. I do not understand few things. I haven't seen the solution anywhere on the new, so this is why i ask here. It is a quantum well - Lx is it's dimension along x-axis Ly is it's dimension along the y-axis.There is a potential as in picture let's call it...
