How photo electric effect happens? According to quantum theory (based upon which the photoelectric effect) is explained, the electrons in an atom are in quantized states. For a given photosensitive material the electrons in the valence shell are having unique quantized energy levels. When a light of suitable energy equal to the energy level of the electron ...
If I'm understanding your question correctly, then the answer is that you actually can't justify the connection of your equations along the quantized direction. In fact, the "bands" in the direction perpendicular to your slab are going to be completely flat, which corresponds to an infinite effective mass in that direction. (The infinity comes from the ...
I studied solid state physics last semester and we learned from "Solid State Physics" by Ashcroft and Mermin, but I assume that you can find these topics in every book about solid state physics.
To my mind, the above explanation (and others commonly presented) is missing an important piece though. In the semi-classical intuition presented, there should never be a preference for spins to align. The reason is that Pauli exclusion slapped on top of a classical picture simply restricts the phase-space of the system, thus reducing entropy. Sure, the ...
I have taught myself and several other people how to understand band diagrams properly and I find that universally (myself included) there is a certain need to "unlearn" things that you may have been mistaught in classes or misunderstood. Major problems occur if one has taken a solid-state physics course which only studied band structure in infinite ...
In a 2deg this is straightforward to measure from the temperature dependence of the shubnikov de haas oscillations, which depends directly on vf.
