Claim Text:
1. An apparatus for epitaxial deposition of a monocrystalline Group III-V semiconductor material, comprising: a source of gallium trichloride as a Group III component reactant; a source of a Group V component reactant; a reaction chamber that receives gas streams of the Group III component reactant and the Group V component reactant; one or more substrates positioned in the reaction chamber to receive a deposit of semiconductor material from reaction of the Group III component reactant and the Group V component reactant; a heating chamber external of the reaction chamber for heating the Group III component reactant to a temperature sufficient to decompose dimers therein as well as to prevent dimer formation of the Group III component reactant prior to contacting the one or more substrates; and a first gas injector operatively associated with the heating chamber and the reaction chamber, the first gas injector comprising:
