Correct Answer <span style=" line-height: 107%; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">Pentavalent impurity</span>

  • The process of adding impurities is called doping.
  • An extrinsic semiconductor is of 2 types: n-type and p-type.
  • When the trivalent impurity is added to an intrinsic or pure semiconductor (silicon or germanium), then it is said to be a p-type semiconductor.
  • Trivalent impurities such as Boron (B), Gallium (G), Indium (In), Aluminum (Al), etc are called acceptor impurity.
  • When a pentavalent impurity is added to an intrinsic or pure semiconductor (silicon or germanium), then it is said to be an n-type semiconductor.
  • Pentavalent impurities such as phosphorus (P), arsenic (As), antimony (Sb), etc are called donor impurity.
