High electric breakdown field
WebElectrical breakdown occurs when the field first exceeds the dielectric strength of the material in some region of the object. Once one area has broken down and become conductive, that area has almost no voltage drop and the full voltage is applied across the remaining length of the insulator, resulting in a higher gradient and electric field, … Web24 de mar. de 2024 · Notably, T150 exhibited an improved average breakdown field of ~ 8.3 MV/cm, which was close to that of T250. The leakage current density characteristics of all the samples are shown in Figure S1 .
