Semiconductor classification

The first generation semiconductor materials mainly refer to silicon and germanium element semiconductor materials;

The second generation semiconductor materials mainly refer to compound semiconductor materials, such as gallium arsenide (GaAs) and indium antimonide (InSb);

The third-generation semiconductor materials are mainly represented by wide bandgap semiconductor materials such as silicon carbide (SiC), gallium nitride (GaN), zinc oxide (ZnO), diamond, and aluminum nitride (AlN).
