Proton Irradiation Induced Defects in 611- and 4H-SiC

  • Werner Puff (a1), Adam G. Balogh (a2) and Peter Mascher (a3)

Abstract

Annealing of defects in proton irradiated bulk n-type 6H- and semi-insulating 4H-SiC has been investigated by positron lifetime spectroscopy and Doppler-broadening measurements. For the n-type sample radiation induced defects in dependence of the proton fluence were studied. Three or four annealing stages were found, during which the formation of larger defect complexes could be observed.
