2.At OK, Germanium behaves as(A) a conductor(C) an insulator(B) an intrinsic semiconductor(D) an extrinsic semiconductor |
|
Answer» Option CSemiconductors act as insulators at low temperatures and conductors at higher temperatures. Conduction occurs at higher temperature because the electrons surrounding the semiconductor atoms can break away from their covalent bond and move freely about the lattice The conductive property of semiconductors forms the basis for understanding how we can use these materials in electrical devices. |
