Investigation of Electron Emission from Metal/Insulator Interface in Vacuum and Eletric Charge on the Insulator

Surface flashover is one of the problems in improving insulation performance in gas, liquid and vacuum. It has been regarded that the emission of electrons from the cathode triple junction (CTJ) is a first step of initiating the surface flashover. Therefore, it is important to investigate field electron emission phenomenon from around the CTJ region with respect to achieving the higher performance...
