A New Model for the DI-Luminescence in 6H-SiC
In a combined theoretical and experimental work, we have investigated the common DI photoluminescence in 6H-SiC material. We present an atomistic model which is able to explain the annealing behavior, i. e. the correlation with the silicon vacancy, the local vibrational modes and the excitonic-like character observed.
