EMA 3413 Final review questions 1. What is the relationship among various physical terms associated with a wave, including energy, wavelength, wave vector, frequency, angular frequency, momentum, and phase and group velocities? 2. What is the importance of the Schrödinger Equation and how can you use it to derive the energy and wavefunction of allowed states given a certain potential field? 3. What are the energy states of free electrons and electrons confined in infinite potential wells? 4. How are electronic bands formed in a crystal and what is main difference between the band structures for metals and semiconductors? 5. What are the Fermi-Dirac distribution and the density of states? How do electrons fill the bands in a metal, a semiconductor, and an insulator differently? 6. What is the main difference when using the classical or quantum electron theory to explain the electrical conductivity of a metal? 7.
