Abstract
We have performed angle-dispersive X-ray powder diffraction experiments on LiGa, LiIn, LiZn, and LiCd at pressures up to 21 GPa using diamond anvil cell techniques. Upon thermal annealing, LiIn and LiCd are both found to undergo phase transformations at a pressure of 11(1) GPa into high-pressure phases with a beta-brass (CsCl) structure. Optical reflectivity measurements indicate metallic behavior of the ambient-pressure phases. Band structure calculations for LiIn confirm the covalent character of the bonding within the diamond-type indium partial structure. The transformation into the CsCl-type phase is associated with a loss of directional In-In bonds. (C) 1998 Academic Press.
