Abstract

We present current–voltage studies of very thin s,77 nmd barium titanate single crystals up to 1.3 GV/m applied field. These show that the mechanism of leakage current at high fields is that of space charge limited conduction sSCLCd in a regime with a continuous distribution of traps, according to the original model of Rose fPhys. Rev. 97, 1538 s1955dg. This study represents a factor of 35 in field compared with the early studies of BaTiO3 conduction.
