Abstract

In-situ high pressure (up to 20 GPa) energy-dispersive EXAFS as well as energy- and angle-disper sive powder diffraction have been used to study phase transformations in bulk amorphous GaSb and (GaSb)(1-x)(Ge-2)(x). Complex transitional behavior was observed. The amorphous-to-high pressure crystalline GaSb II phase transition starts at a pressure of approximate to 4 GPa, whereas the analogous transition in crystalline GaSb takes place at around 7 GPa. The abnormally large Debye-Wallerfactor for Ga nearest neighbors in the high pressure phase is interpreted in terms of the existence of an orthorhombic structure. In the solid solutions of GaSb with Ge the transition pressure shifts to highervalues with increasing Ge concentration x.
