- W2035172203 abstract "A real-time change in the absorption strength of the $text{Si}--mathrm{H}$ stretching vibration in hydrogenated amorphous silicon $(atext{ensuremath{-}}text{Si}:mathrm{H})$, so-called modulated IR-absorption, is observable when $atext{ensuremath{-}}text{Si}:mathrm{H}$ is illuminated with modulated band-gap light at low-temperature. This IR-absorption change should reflect a change in a structural configuration at the local surroundings of the $text{Si}--mathrm{H}$ bond, since the band-gap light does not directly affect the localized vibrational mode. We have utilized this phenomenon as a sensor for detecting the real-time structural instability in the vicinity of the bonded hydrogen. Following a previous study on a difference in the structural instability between the surroundings of $text{Si}--mathrm{H}$ and $text{Si}--{mathrm{H}}_{2}$ bonds in updoped $atext{ensuremath{-}}text{Si}:mathrm{H}$ [H. Oheda, Phys. Rev. B 68, 085206 (2003)], the present study extends the investigation to $atext{ensuremath{-}}text{Si}:mathrm{H}$-based wide-gap alloys, such as $atext{ensuremath{-}}text{SiN}:mathrm{H}$ and $atext{ensuremath{-}}text{SiO}:mathrm{H}$. In particular, it is concerned with how the structural instability around the $text{Si}:mathrm{H}$ bond is affected by a change in the structural configuration at the local surroundings of the $text{Si}:mathrm{H}$ bond due to neighboring of alloy atoms. It is found that the magnitude of the modulated IR-absorption, or the structural instability, is reduced as the number of neighboring alloy atoms increases. An examination of the spectral difference between the modulated IR-absorption and the corresponding normal IR-absorption shows that the structural instability takes place more effectively at the specific site where the $text{Si}--mathrm{H}$ bond is surrounded by two or three nearest-neighbor Si atoms. The change in strength of the local strain around the $text{Si}--mathrm{H}$ bond, due to the neighboring of alloy atoms, is a major cause of the site-dependent structural instability in the wide-gap alloys." @default.
