Electron paramagnetic resonance (EPR) and optical absorption studies of defects created in diamond by electron irradiation damage at 100 and 350 K

Abstract:

We present a study, using electron paramagnetic resonance (EPR) and optical absorption spectroscopies, of high purity synthetic type IIa diamonds, which have been irradiated with 2 MeV electrons in a specially developed dewar; allowing irradiation at a measured sample temperature down to 100 K, at doses of 2 x 10(17) --> 4 x 10(18)e(-) cm(-2). The production rate of vacancies (1.53(10) cm(-1)) was the same for irradiation at 100 as at 350 K; as was the production rate of the EPR centre R1,...
