Question

Choose the semiconductor from the following:

• A. Silicon
• B. Silicate
• C. Silicon dioxide
• D. Silica

Answer 1

Answer:

A. Silicon

• 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
