Gas Release of SiC Implanted with Deuterium or Helium
Abstract:Helium (He+) or Deuterium (D2+) (20 keV) was implanted into polycrystalline -SiC with an ion dose of 7.2 × 1021 (D or He)/m2. The implanted specimens were heated at a heating rate of 10 or 20 K/min from room temperature to 1373 K, and the thermal release spectroscopic data were obtained. A sharp peak appeared at approximately 1270 K in the case of He release, and here the activation energy was estimated to be approximately 4.4 eV. Two overlapped peaks appeared at approximately 900 and 1200 K in the case of D2 release. The shapes of spectra showed strong dependence on the heating rate.
