摘要
Control of hydrogenation and modulation of the structural network in Si:H is proposed by growth interruption and H-plasma exposure on stacking layers. Hydrogen incorporation as well as elimination are both possible through subsurface reactions by atomic hydrogen of the plasma. An increase in the optical gap due to rehydrogenation is obvious; however, widening in the optical gap during dehydrogenation of the network appears to be a unique feature which may suggest nanocrystallization and quantum size effects in the hydrogenated binary alloy. At the onset of nanocrystallization, a significant improvement in light-induced degradation has been observed. A wide range of temperatures to fabricate good quality equilibrated films could be provided by interrupted growth and H-plasma exposure technique. © 1995 The American Physical Society.
