|Title:||Structural Properties Of Deuterated Germanium Nitrogen Alloys|
|Abstract:||An infrared analysis of nonstoichiometric hydrogenated and deuterated germanium-nitrogen alloys is presented. The films were prepared by rf reactive sputtering of a c-Ge target in a gas mixture of Ar+N2+(H2 or D2). The isotopic effect was used to identify the absorption bands associated with the alloy elements bonded to hydrogen. Its infrared spectra pattern depends strongly on the preparation condition. Samples prepared in the 100-300°C temperature range are stable, while those prepared at temperatures lower than 100°C show spontaneous atmospheric contamination. In this case, the evolution of the infrared spectra with the atmosphere exposing time for hydrogenated and deuterated films was analyzed.|
