Q:What is an electron/hole pocket and what is the significance? I'm trying to get my head around this. I've read what Ashcroft and Mermin have to say on the subject, but it's a little convoluted. They talk about the 1st, 2nd, 3rd, etc Brillouin Zones (BZ), and then show that,...
current also results from electron movement, however, the movement is based on electron deficiencies in atoms. An electron-deficient atom in a semiconductor is called ahole. In this case, the current moves from
Transistors (portmanteaux of “transmitter” and “resistor”) rely on a quirk of quantum mechanics known as an “electron hole.” A hole is the lack of an electron at a spot where one could exist in semiconducting material. By introducing an electric signal to a transistor, electric fields...

What is electron, it is the lightest stable subatomic particle. It has a negative charge that is the basic unit of the electric charge. The mass of an electron at rest is 9.10938356 x 10-31 kg that is only 1/1,836 the mass of a single proton.
For a black hole to form, the star must be a massive star and is usually not in the main-sequence stars on the H-R diagram. As the star collapses, it pulls in all matter around it and becomes an extremely dense point in space. It becomes so powerful and so dense, that not even ...
Just like the CRT it has an electron gun in the back. A coil called a “helix” is wound around the electron beam, the input of the tube is connected to the end of the helix closer to the electron gun and the output is taken from the other end. The radio wave flowing through the...
