Gallium arsenide (GaAs) is used in power amplifiers and high-frequency applications. It is expected that the demand for 5G will expand strongly. The major manufacturers are Sumitomo Electric and AXT. In terms of silicon carbide (SiC), in addition to power components, the demand for semi-insulation categories such as communication infrastructure has greatly increased. Silicon carbide products are mainly used in electric vehicles.
