Abstract
Localization of electrons on hydrogenic impurity atoms in Si and Ge and their delocalization by electric field breakdown of the localized states were examined on the insulating side of a strain-induced metal-nonmetal transition. Both nonlinear and linear dependencies of the breakdown field on activation energy were obtained. Experimental results were explained taking into account a crucial transformation of silicon and germanium conduction band structure under extremely high uniaxial pressure.
