NonGaAs
NonGaAs refers to semiconductor materials and devices that do not use gallium arsenide as the primary semiconductor. The category encompasses a broad range of materials, including silicon (Si), silicon carbide (SiC), gallium nitride and related aluminum gallium nitride (GaN/AlGaN), indium phosphide (InP), and indium gallium arsenide (InGaAs), as well as other IV–VI and III–V compounds. These materials offer different electronic and optical properties, such as bandgap energy, carrier mobility, thermal conductivity, and lattice constants, enabling technologies beyond those available with GaAs.
Silicon is the most widely used non-GaAs material, forming the basis of integrated circuits and solar cells
Selection among nonGaAs materials depends on factors such as desired bandgap, speed, power handling, temperature tolerance,
