If n> P, it becomes n-type semiconductor. If n In intrinsic semiconductors, the product of electrons and holes is a constant. This formula is true even for Doped Semiconductors in heat balance. (I think this formula is very important)In N-type semiconductors, the concentration of free electr
1. drifting current
When a certain electric field is applied to a semiconductor, the current flows through the semiconductor. When a particle with a dot moves in the electric field, the resulting current becomes the drifting current.
2. Mobility
When the electric field strength is low, the carrier's drift speed V is proportional to the electric field strength E. The proportional constant is called the mobility.
3. Rate saturation
The carrier speed cannot increase infinitely and cannot
