Title: Oxide Transistors with Conventional High-k Dielectric or Ferroelectric Dielectric
Presenter: Peide Ye (School of Electrical and Computer Engineering, Purdue University)
Abstract: In this talk, we report on the experimental demonstration of robust beta-gallium oxide (β-Ga2O3) ferroelectric (FE) field-effect transistors (FeFETs) on a sapphire substrate operated up to 400 °C. Atomic layer deposited (ALD) Hf0.5Zr0.5O2 (HZO) is used as the ferroelectric FE dielectric. The HZO/β-Ga2O3 FeFETs are studied for their synaptic behavior applications at elevated temperatures. We will also extend the β-Ga2O3 to other transition-metal-oxides such as sputtered indium-tin-oxide and atomic-layer-deposited (ALD) In2O3 as channels showing outstanding transistor characteristics with conventional high-k dielectric as thin-film transistors or ferroelectric dielectric as FeFETs.
