ABSTRACT

Most of the III-V semiconductor compounds have the zincblende structure. Table 1 shows the bandgap energy, lattice parameter, refractive index, dielectric constant, conduction band effective mass and valence band effective masses of some of the binary III-V compounds. These binary semiconductors are generally useful as substrates and some binary, ternary and quaternary alloys of these compounds have certain useful characteristics. Some of the ternary and quaternary alloys are lattice matched to certain binary compounds with different bandgap energies providing interesting physical properties.
