Abstract Scope |
Perovskite nickelates are highly promising for a range of applications in microelectronics, including transistors, memory devices and beyond because of their tunable electronic, magnetic and optical properties driven by strong electron correlation. In this talk, I will discuss our recent work on the hydrogen induced resistive switching (RS) characteristics in SmNiO3 epitaxial thin films deposited on Nb doped SrTiO3 (001) substrates. The high quality epitaxial SmNiO3 films were deposited by using pulsed laser deposition technique. Hydrogen doping in SmNiO3 was achieved by using Pt as catalyst that dissociates molecular hydrogen into proton (H+) and biasing was applied to facilitate the H+ doping process. Interestingly, the hydrogen doped SmNiO3 thin film exhibits reversible RS characteristics with prominent current-voltage hysteresis which is not present in the pristine film. We expect that the migration of H+ near the interface between Pt and SmNiO3 is responsible for such RS properties. |
