Mechanism Of The Free Charge Carrier Generation In The Dielectric Breakdown

Many studies have been conducted to investigate the effect of environmental,mechanical and electrical stresses on insulator.However,studies on physical process of discharge phenomenon,leading to the breakdown of the insulator surface are lacking and difficult to comprehend.Therefore,this paper analy...
