Ntype extrinsic semiconductors attribute their conductive to

N-type extrinsic semiconductors attribute their conductive to properties mainly due to which charge carriers? electrons and holes holes electrons protons Corrosion can be prevented or slowed down by choosing a metal that passivates in a particular environment. Passivation involves which of the following? Increased current from the anodic reaction Application of a polymer coating to the metal Formation of a protective oxide on the metal Adding inhibitors to the electrochemical environment

Solution

8) electrons

9)formation of protective oxide on the metal
