http://newport.eecs.uci.edu/~rnelson/files-2008/Student_Presentations/High-K_Dielectric_2.ppt Webthe dielectric strength of a solid dielectric increases very rapidly to an upper limit called the intrinsic electric strength. Intrinsic breakdown depends upon the presence of free electrons which are capable of migration through the lattice of the dielectric. Usually, a small number of conduction elections are present in solid
