Question

What is an intrinsic semiconductor?

विकल्प

• A semiconductor with intentionally added impurity atoms.

• A semiconductor whose conductivity is higher than an extrinsic semiconductor.

• A pure semiconductor in which no impurity is added intentionally.

• A semiconductor in which one type of charge carrier is usually the majority carrier.

Answer 1

An intrinsic semiconductor is chemically pure: no impurity is added intentionally. Pure silicon and pure germanium are examples.
