Duane Windsorlectron Mobility Transistor: HEMT) are discussed by solving Schrödinder equation, and then transport properties are described by evaluating scattering rate and mobility. Basic idea of superlattices is given by showing Kronig-Penney model and Brillouin zone folding effect. In order to explain the opt

Manuel Hensmans,Guangyan Liuconnect absorption with spontaneous emission and stimulated emission. Then the spontaneous and stimulated emission rates are derived from the perturbation theory. Absorption and emission rates are strongly affected by the density of states, The density of states in the presence of impurities are sho
