M. Bernasconi et al., AB-INITIO CALCULATIONS OF STRUCTURAL AND ELECTRONIC-PROPERTIES OF GALLIUM SOLID-STATE PHASES, Physical review. B, Condensed matter, 52(14), 1995, pp. 9988-9998
Structural and electronic properties of various solid-state phases of
gallium have been studied by means of first-principles total-energy ca
lculations. Our results confirm that while the ground state alpha phas
e is characterized by the notable coexistence of metallic and covalent
characters, the other phases are totally metallic. We predict that a
phase transition from GaII to fee should be observable at pressure sim
ilar to 150 kbar.
