Why silicon and germanium are semiconductors

Silicon-germanium serves as a semiconductor in integrated circuits for heterojunction bipolar transistors or as a strain-inducing layer for CMOS transistors. Here heterojunction refers to the interface between two layers or regions of dissimilar crystalline semiconductors. The two semiconducting materials have unequal band gaps.
