摘要: Number of Cu atom(s) in the 1.014 eV copper center silicon crystal was determined from an accurately measured relationship between photoluminescence (PL) intensity and concentration crystal. For concentrations lower than about 1×1014 atom/cm3, PL increased linearly with increasing concentration. From this result law mass action, it concluded that had only one atom it, contradicting long-believed pair model. Based on already published data present result, a structural model which bonded at Si–Si bond presented for center.
