Numerical model for electrical charge injection in the acoustic charge-transport device

Space Charge Modulated Electrical Breakdown

“…After the establishment of pulsed electro-acoustic (PEA) method in 1990s, space charge distribution in solid insulating materials came to be intuitively demonstrated 15 . During the same period, numerical simulations of space charge profiles were initially performed 16 17 and some of the simulated results could perfectly match the PEA results in recent years 18 . As a result of the development in understanding space charges, the electric field concentration and distortion induced by space charges were valued and considered as an important factor that modifies the dielectric behaviour of insulating materials 19 20 .…”
