Question

what are n-type and p-type semiconductor​

Answer 1

Answer:

Explanation:

N-type semiconductors are created by doping an intrinsic semiconductor with an electron donor element during manufacture.  In n-type semiconductors, electrons are the majority carriers and holes are the minority carriers. A common dopant for n-type silicon is phosphorus or arsenic.

P-Type Semiconductor-The addition of trivalent impurities such as boron, aluminum or gallium to an intrinsic semiconductor creates deficiencies of valence electrons, called "holes". It is typical to use B2H6 diborane gas to diffuse boron into the silicon material.
