The Response of Germanium to Large Amplitude Shock Waves.

Abstract

A tentative explanation for the first two (50 kb and 120 kb) experimentally observed shock wave transitions in single crystal germanium is presented. Calculations are carried out which suggest that the 120 kb transition is associated with the ductile yielding upon collapse of the conduction band onto the valence band (i.e., a semiconductor-metal transition without an associated transformation of the crystal structure). Arguments are also given which lead to the identification of the 50 kb transition as a brittle fracture phenomenon. (Author)
