What is Extrinsic Semiconductor?
The devices like diodes, transistors, ICs used in electronic circuits are manufactured with the help of extrinsic semiconductor. When a trivalent or pentavalent element is mixed with pure Silicon crystal (i.e. intrinsic semiconductor), the new material is formed known as extrinsic semiconductor.
What is Intrinsic Semiconductor?
The pure crystal of semiconductor (Si or Ge) is known as intrinsic semiconductor at room temperature. The Silicon atom has 14 electrons revolving around its nucleus. In first orbit it contains 2 electrons, in second orbit 8 electrons i.e. 4 electrons in last orbit, known as valence electrons.
What is Conductor, insulator & semiconductor?
Some substances like Germanium, Silicon, Carbon, etc. are neither good conductors like copper nor insulators like glass. The resistivity of these materials lies in between conductors and insulators. Such substances are known as semiconductors.
