Difference Between Intrinsic and Extrinsic Semiconductor
Here are the main differences between Intrinsic and Extrinsic Semiconductor:
Intrinsic Semiconductor | Extrinsic Semiconductor |
|---|---|
intrinsic semiconductor is a pure semiconductor material like silicon or germanium. | An extrinsic semiconductor has added impurities (dopants) to change its electrical properties. |
In intrinsic semiconductors, thermal energy moves electrons to the conduction band, creating electron-hole pairs. | Extrinsic semiconductors can be N-type (more electrons) or P-type (more holes), based on the additives used. |
At typical temperatures, intrinsic semiconductors exhibit low conductivity due to the constrained count of charge carriers generated by thermal effects. | Extrinsic semiconductors have much higher conductivity than intrinsic ones because doping adds more charge carriers. |
Intrinsic semiconductors have a relatively large energy gap between their valence and conduction bands compared to extrinsic semiconductors. | Doping can also marginally alter the energy gap of extrinsic semiconductors, particularly in the presence of specific additives. |
Intrinsic semiconductors aren’t very conductive, so they’re not used much in devices. But they’re important for understanding how semiconductors work. | Extrinsic semiconductors are used in many electronics like transistors and solar cells because they have controllable high conductivity. |
Semiconductors
A Semiconductor is a kind of material that performs conductivity between conductors and insulators and has a conductivity value that lies between the conductor and an insulator.
