EVALUATION OF ZN(N[SI(CH3)3]2)2 AS A P-TYPE DOPANT IN OMVPE GROWTH OF ZNSE

We have grown nominally undoped ZnSe on GaAs from the precursors H2Se and Et2Zn. Replacement of Et2Zn by Zn[N(TMS)2]2 produced crystalline ZnSe of a lesser quality. Data indicate incorporation of nitrogen into the films when Et2Zn is utilized as the main zinc source with Zn[N(TMS)2]2 being introduced at dopant levels. Characterization techniques employed include NMR, XRD, SIMS, SEM, PL, RGA, GC/MS, and Raman spectroscopy.
