Research Themes

Preparation of Ferroelectric Films by Pulsed Laser Ablation for NVRAM

Preparation of Ferroelectric Films by Pulsed Laser Ablation for NVRAM For establishing the oxide electronics my interest is on the thin film fabrication by pulsed laser ablation (PLA) technique. The PLA is carried out by focusing the pulsed laser beam onto the target. Target materials melted and ejected by high power density laser are transferred to the substrates, resulting in designed crystalline films. Materials for nonvolatile memory, which does not lose the memory without an electricity supply, are grown and characterized.
