Question

which type of semiconductor is created by doping with atoms that contain more valence electrons than the semiconductor material?
a) n - type
b) intrinsic
c) p - type
d) intrinsic and p - type

Explanation:

To determine the type of semiconductor created by doping with atoms having more valence electrons:

• Intrinsic semiconductors are pure, undoped, so B and D are incorrect.
• P - type semiconductors are doped with atoms having fewer valence electrons (acceptors, creating holes).
• N - type semiconductors are doped with atoms (donors) having more valence electrons, which donate extra electrons (negative charge carriers), matching the description.

Answer:

A) N - type
