Abstract : The research project which has been initiated by Michael Mosscrop involves an investigation of the effects of the substituents on the cyclopentadienyl ring on the chemistry of compounds of the type R2GaCp, RGaCp2 and GaCp3 (R = Me, Et; Cg = any substituted cyclopentadienyl moiety). These compounds are being investigated as potential precursors to the gallium(I) intermediate, GaCp. Earlier work by others in the research group demonstrated that low oxidation state species react with elemental phosphorus to form materials at unusually low temperature. For example, In(C5Me5) reacts with P4 to form InP at 125 deg C under OMCVD conditions. Thus, the goal is to determine if R2GaCp type compounds decompose selectively and readily to form GaCp and then react with phosphorus to form materials such as GaP at significantly lower temperatures that those typically employed in OMCVD, i.e. 600-800 deg C. jg p.3
