웹2011년 2월 22일 · For example, such a one-valley bandgap fit is used in the case of the technologically important strained Si Ge grown on Si (see Fig. 3.11).In certain cases for the bandgap can become smaller than the one of pure Ge [] depending on the strain.In the unstrained case, however, an -to-gap transition is observed at about .. The material … In solid-state physics, a band gap, also called a bandgap or energy gap, is an energy range in a solid where no electronic states exist. In graphs of the electronic band structure of solids, the band gap refers to the energy difference (often expressed in electronvolts) between the top of the valence band and the bottom … 더 보기 Every solid has its own characteristic energy-band structure. This variation in band structure is responsible for the wide range of electrical characteristics observed in various materials. Depending on the dimension, the band … 더 보기 In materials with a large exciton binding energy, it is possible for a photon to have just barely enough energy to create an exciton (bound electron–hole pair), but not enough energy to separate the electron and hole (which are electrically attracted to each other).
