摘要：

4H-SiC samples were implanted at room temperature with 30 keV D+ ions at a dose of 5x10(16) D+/cm(2). Nuclear reaction analysis (NRA) and secondary ion mass spectroscopy (SIMS) measurements were performed to study the deuterium profiles after subsequent annealing at 1000-1250degreesC for 10min.Also, analytical techniques: RBS/C and thermal desorption spectroscopy (TDS) were carried out to characterize the evolution of implantation induced defects upon annealing. According to the NRA, measurements, no deuterium release was found in the sample annealed at 1000degreesC. However, increasing the temperature. to 1150degreesC led to a 40% decrease of deuterium content. Similar results about the evolution of D profiles upon annealing have also been obtained by SIMS measurements. In addition, SIMS measurements show that the maximum of the deuterium concentration. shifts to the surface. Deuterium desorption at annealing temperatures higher than 1000degreesC was further confirmed by TDS experiments. Results from RBS/C indicated that during the desorption of deuterium, the implantation induced damage was annealed. These results are discussed.
