【Abstract】 Abstract In this paper, it is supposed for the first time that there are two types of quinary semiconductors, and using cubic figure to illustrate their component space. The equations to calculate the lattice constant, bandgap energy and misbility gap of quibnary are derived. As an example, the equal bandgap energy line and misbility gap at different temperatures of AlGaInPAs/GaAs latticed matched material system is calculated and illustrated.更多还原
