Surface flashover of silicon [PDF]
IEEE Transactions on Electron Devices, 1990 Empirical information about surface flashover of silicon in a vacuum ambient which shows that in breakdown the current is carried primarily inside the semiconductor is presented. This observation shows that the physical processes responsible for flashover of silicon are fundamentally different from those assumed in the standard model for flashover of ...
