Question

In n-type semiconductor majority carriers and minority carriers are respectively ______.

Options

• electrons and holes

• aluminum and boron

• holes and electrons

• germanium and silicon

Answer 1

In n-type semiconductor majority carriers and minority carriers are respectively electrons and holes.

Explanation:

The electron concentration in N-type semiconductors is higher than the hole concentration. The word n-type refers to the electron's negative charge.

Electrons are the majority carriers in n-type semiconductors, while holes are the minority carriers.

N-type semiconductors are made by doping donor impurities into an inherent semiconductor (or doping a p-type semiconductor as done in the making of CMOS chips). Phosphorus is a frequent dopant for n-type silicon.
