AbstractThe dependence of the creation and the annealing of metastable dangling bonds in hydrogenated amorphous silicon on various material parameters will be discussed in the context of a recently proposed model. After a brief review of the kinetic behaviour governing defect creation and annealing in undoped a- Si:H, a number of special cases will be analyzed: the influence of alloying with O, N, C, and Ge, changes introduced by doping and compensation, and the role of mechanical stress. Finally, possibilities to increase the stability of a-Si:H based devices will be examined.

Photoluminescence (PL) from Er-implanted hydrogenated amorphous silicon suboxide ( a - SiO X : H 〈 Er 〉( x <2.0)) films was measured. Two luminescence bands with maxima at λ ≅ 750 nm and λ ≅ 1.54μ m, ascribed to the a - SiO x : H intrinsic emission and Er 3+ emission, were observed. Peak intensities of the two bands follow the same trend as a function of annealing temperature from 300 to 1000°C. Micro-Raman results indicate that the a - SiO x : H < Er > films are a mixture of two phases, an amorphous SiO x matrix and amorphous silicon (a-Si) domains embedded there in. FTIR spectra confirm that hydrogen effusion from a - SiO x : H < Er > films occurs during annealing. Hydrogen effusion leads to a reconstruction of the microstructure of a-Si domains, thus having a strong influence on Er 3+ emission. Our study emphasizes the role of a-Si domains on Er 3+ emission in a - SiO x : H < Er > films.
