    • note
    • It should be recognized that there was much other work done on a-Ge:H at around the same time (see Refs. 32-37). This work, however, was not explicitly motivated as an approach to improving the alloys, and achieved only moderate enhancements in the properties of a-Ge:H. More recently, there has been some success in producing a-Ge:H comparable to that discussed here using dc magnetron sputtering (Ref. 38) and the "hot wire" technique (Ref. 39).

    • Converting subgap optical absorption quantitatively into density of midgap states is very problematic (see Ref. 59). At best, subgap absorption should be used to make rough relative comparisons of the midgap state density.

    • The decrease is, in fact, worse if we take into account the fact that the ημτ for anodic a-Ge:H is increased by air contamination effects which occur when the sample is transferred to the measurement apparatus [see Y. M. Li, W. A. Turner, C. Lee, and W. Paul, Mater. Res. Soc. Symp. 149, 187 (1989)].

    • It should be noted, however, that through the use of apparatus with much higher detectivity than ours, PL for anodic a-Ge:H can be observed and has been studied by others (Refs. 4, 77, and 79).

    • This structure appears homogeneous to all measurement techniques except SAXS, in which a low level of scattering due to atomic-scale diffuse scattering and some larger-scale residual heterogeneity is observed (Ref. 53).

    • note
    • Simple theoretical expressions are obtained for Laue scattering due to random alloying (Ref. 53). Deviations from predicted values may be attributed to atomic-scale clustering or ordering. No evidence has yet to be found for such deviations for the alloys presented here (see Ref. 91).
