摘要
The aerosol-assisted chemical vapour deposition (AACVD) of CdTe has been carried out using Cd[(TePiPr(2))(2)N](2) at substrate temperatures between 375 and 475 degrees C. XRD shows the formation of cubic CdTe between 425 and 475 degrees C. At low deposition temperature (375 degrees C), a mixture of hexagonal tellurium and cubic cadmium telluride is observed. SEM images reveal that the growth temperatures do not have a profound effect on the morphologies of films. Surface analysis by XPS of films deposited at 475 degrees C showed the growth of Te-rich films. The AACVD of Hg[(TePiPr(2))(2)N](2) resulted in deposition of hexagonal tellurium.
