dc.description.abstractFerroelectric films are being developed for use in DRAMs. However some commercially promising materials suffer fatigue problems that are likely to be related to stoichiometric changes. Heavy ion recoil spectrometry employing 77 and 98 MeV 127I ions has been used to analyse thin films of barium strontium titanate (BST) at the new heavy ion recoil facility at ANSTO, Lucas Heights. The technique employs a Time of Flight and Energy (TOF-E) detector which enables the determination of separate energy spectra for individual or small groups of elements. Depth profiles for all major elements and carbon have been obtained. Analysis reveals depletion of oxygen in the BST layer next to the platinum electrode and interdiffusion of strontium and oxygen through the layers.
