Abstract
The basic effect of pressure is to increase overlap between adjacent electronic orbitals. There are a number of consequences of this increased overlap. In the first order, there is a delocalization of electrons, a broadening of the bands of allowed energy and a decrease in magnitude of the gaps of forbidden energy between bands. For an insulator or semiconductor there is a decrease in resistivity which may ultimately lead to metallic behavior. This is the classical picture observed in books like that of Seitz [1].
