Thermal stability of the optical band gap and structural order in hot-wire-deposited amorphous silicon

Author: Arendse, CJ ; Malgas, G ; Oliphant, CJ ; Muller, TFG ; Knoesen, D Date: 2009 The material properties of hydrogenated amorphous silicon (a-Si:H) have been known to change when exposed to elevated temperatures. In this work researchers report on the thermal stability of the optical band gap and structural disorder in ... Read more
Thermally induced nano-structural and optical changes of nc-Si:H deposited by hot-wire CVD

Author: Arendse, CJ ; Malgas, GF ; Muller, TFG ; Knoesen, D ; Oliphant, CJ ; Motaung, DE ; Mwakikunga, Bonex W Date: Apr 2009 This paper reports on the thermally induced changes of the nano-structural and optical properties of hydrogenated nanocrystalline silicon in the temperature range 200–700 °C. The as-deposited sample has a high crystalline volume fraction of ... Read more
