Abstract Equilibrium calculations have been performed on systems containing arsine, trimethyl gallium, hydrogen and the dopants for GaAs. The aim was to find out whether unwanted solid compounds of the doping elements are to be expected on thermodynamic grounds.

equilibria (liquid + GaN + gas)were selected for the assessment. It was believed that this type of experimental data was collected at the conditions close to equilibrium, as opposed to the possibly metastable twophase (GaN + gas)data for which the kinetic barrier might have prevented or delayed formation of liquid gallium droplets.

Gallium. Definition. Gallium is a rare, silvery metallic element that is found as a trace element in coal, in bauxite, and in several minerals. It is liquid near room temperature and expands when it solidifies. Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in .

prevent the liquid from adopting an equilibrium shape. Alloys of gallium are no exception; the oxide can stabilize the metal in nonequilibrium shapes (27) despite being quite thin [∼1nm in dry air (25, 28, 29)]. To achieve spreading, an electrochemical driving force is necessary. Although it is conceivable that spread
