First of all, the recently hot third generation semiconductor refers to the third generation of semiconductor materials.

The first generation of semiconductor materials: The first generation of semiconductor materials mainly refers to silicon (Si), germanium element (Ge) semiconductor materials. At first, germanium was used more, and later silicon materials were more suitable and better developed, and silicon is now the most commonly used material for semiconductors.

The second generation of semiconductor materials: The second generation of semiconductor materials is represented by gallium arsenide (GaAs) and gallium phosphide (GaP). It is the material of most communication equipment in the 4G era.

The third generation of semiconductor materials: Gallium nitride (GaN), silicon carbide (SiC), zinc oxide (ZnO), diamond as the four representatives.

In fact, using the third generation of semiconductors will cause misunderstanding, in fact, the third generation of semiconductors to the first and second generation does not have the so-called iterative replacement meaning, because most of them are used in different fields.

Silicon is still the best choice for traditional digital chips, analog chips, cpus, and Gpus. The third generation of semiconductor materials GaN SiC is used in the field of power semiconductors, radio frequency and optoelectronic devices.
