High-Speed III-V Semiconductor Devices,as MESFETs and HEMTs are presented. The devices described here include GaAs- and InPbased metal–semiconductor field-effect transistors (MESFETs) and high electron mobility transistors (HEMTs). The GaAs-based high-speed devices are fabricated using the lattice-matched GaAs/AlGaAs material system grow

Classification of Solids and Crystal Structure,entimeters. A polycrystalline solid contains many of these small single-crystalline regions surrounded by the grain boundaries. Distinction between these two classes of solids—amorphous and crystalline—can be made through the use of X-ray or electron diffraction techniques.

Lattice Dynamics,such a solid results entirely from its lattice vibrations. On the other hand, the specific heat for metals is dominated by the lattice-specific heat at high temperatures, and by the electronic specific heat at very low temperatures. The most important effect of the lattice vibration on metals or int

Energy Band Theory,even though the problem is confined as a purely electronic one, there are still the many-electron problems in the system that cannot be solved explicitly. Therefore, it is necessary to apply additional approximations in solving the Schrödinger equation for electrons in a crystalline solid.
