Question:
Choose the semiconductor from the following:
ASilicon
BSilicate
CSilicon dioxide
DSilica
Answer:
A. Silicon
Explanation:
Silicon atomic number is 14
Valancy is 4
Semiconductors can be broadly classified into Intrinsic and Extrinsic Semiconductors
Intrinsic Semiconductors start conducting at temperatures above the room temperature, developing important electronic devices using these can pose a problem
This led to a need for improving the conductivity of intrinsic semiconductors
