Abstract

Hydrogen NMR spectra and spin lattice relaxation times have been obtained as a function of temperature for a-Si:H that had been sequentially annealed up to 600C, for μc-Si:H, and for a-Si_1-xGe_x: H alloys. These three materials differ from dense-grade a-Si:H in that they have more and larger voids containing larger quantities of non-bonded molecular H₂. The low density, intergranular regions in μc-Si:H provide more interconnected, open space than do the voids in annealed a-Si:H and in the Ge rich alloys.
