Abstract : Description of scientific research goals is as follows: induce low energy ion bombardment related effects in ferroelectric thin films, to enhancing the oxygen incorporation efficiency to modify the properties; understanding space-charge related effects on polarization switching phenomena; understanding and correlation of intrinsic multi-tunneling process across heterojunctions in ferroelectric thin films; establish correlation between low energy oxygen ion bombardment to space-charge and heterojunction based conduction and their impact on polarization switching; correlation of switching mechanism via write voltage time dependence to the low energy induced property modifications.
