The M center in 4H-SiC, a bistable defect responsible for a family of electron traps, has been deprived of a model which could unveil its real importance for almost two decades. Using advanced first-principles calculations and junction spectroscopy, we demonstrate that the properties of M, including bistability, annealing, reconfiguration kinetics, and electronic levels match those of the carbon self-interstitial.}, title = {M center in 4H-SiC is a carbon self-interstitial}, volume = {103}, year = {2021} }
