When does intrinsic semiconductor become an extrinsic semiconductor? Illustrate.
Semiconductor doping is the process which changes an intrinsic semiconductor to an extrinsic semiconductor. During doping, impurity atoms are introduced to an intrinsic semiconductor. Impurity atoms are atoms of a different element than atoms of the intrinsic semiconductor. Impurity atoms act as either acceptors or donors to the intrinsic semiconductor, changing electron and hole concentrations of the semiconductor.

Deodorants: Just as the name suggests, deodorants are applied basically to mask the body odour. The body odour provides from the bacterial action subsequent perspiration. Hence
my question is what is difference between relative atomic mass and atomic mass unit.
Tempering is a heat treatment method for metals and alloys. In steels, tempering is completed to "toughen" the metal by transforming brittle marten site into bainite or a combinat
