How may the conductivity of an intrinsic semiconductor be increased ?

Text Solution

AI Generated Solution

To increase the conductivity of an intrinsic semiconductor, we can follow these steps: ### Step 1: Understand Intrinsic Semiconductors - **Definition**: Intrinsic semiconductors are pure semiconductors that do not contain any significant dopant species. They have a balanced number of charge carriers (electrons and holes) at absolute zero temperature. ### Step 2: Doping - **Explanation**: Doping involves introducing impurities into the intrinsic semiconductor to enhance its conductivity. - **P-type Semiconductors**: When elements from Group 13 (like Boron) are added, they create holes (positive charge carriers). ...
