Question

what do you mean by doping? why doping is done in semiconductor​

Answer 1

Answer:

to fall or move to a position that is lower, farther back, inferior, etc.: to drop back in line; to drop to the rear. to withdraw; quit (often followed by out or from): to drop out of a race; to drop from a game.

Explanation:

In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor. ... Doping is also used to control the color in some pigments.

Answer 2

Answer:

Explanation:

Doping is the process of adding impurities to intrinsic semiconductors to alter their properties. Normally Trivalent and Pentavalent elements are used to dope Silicon and Germanium. When an intrinsic semiconductor is doped with Trivalent impurity it becomes a P-Type semiconductor. The P stands for Positive, which means the semiconductor is rich in holes or Positive charged ions. When we dope intrinsic material with Pentavalent impurities we get N-Type semiconductor, where N stands for Negative. N-type semiconductors have Negative charged ions or in other words have excess electrons in it.

doping is done in semiconductor in order to increase their conductivity, as normally they have very little conductivity because the band gap between Valence and conduction band is large.
