摘要

In this paper we revisit sharp low temperature luminescence lines (LTPL) previously generated by high dose 10~(18)to 10~(20) cm~(-2) electron beams in an electron microscope and now produced by low dose 10~(15) cm~(-2) electron, 5×l0~(10) cm~(-2) proton and helium ion irradiation. New no phonon lines E_0, F_0, θ_0, Φ_0, K_0, G_0, J_0, M_0 and phonon replicas are found. Phonon replicas up to the fifth harmonic are well accounted for by theory giving convincing new evidence that the di-carbon antisite is responsible for these deep defect lines.
