|Title:||Hydrogen In Amorphous Germanium-carbon|
|Abstract:||This work shows the study of the hydrogen influences in the structural properties of amorphous germanium-carbon alloys prepared by the RF cosputtering technique. The films were prepared in the all range of carbon content, from 0-100 at.%. The study of hydrogen properties was performed using thermal desorption, infrared and Raman spectroscopes. All the samples have total hydrogen content smaller than 25 at.%, indicating that the films have low presence of polymeric sites, bonded to germanium and carbon. The effusion spectra indicate that the hydrogen atoms are strongly bonded to germanium and carbon. The exo-diffusion promotes the increase in the concentration of germanium-carbon bonds, and graphite clusters. © 1999 Elsevier Science S.A. All rights reserved.|
