Electrical switching dynamics and broadband microwave characteristics of VO2 RF devices
Sieu D. Ha, You Zhou, Christopher J. Fisher +2
Vanadium dioxide is a correlated electron system that features a metal-insulator phase transition (MIT) above room temperature and is of interest in high speed switching devices. H…
Electrostatic gating of metallic and insulating phases in SmNiO3 ultrathin films
Sieu D. Ha, Ulrich Vetter, Jian Shi +1
The correlated electron system SmNiO3 exhibits a metal-insulator phase transition at 130 °C. Using an ionic liquid as an electric double layer (EDL) gate on three-terminal ultrathi…
Hall effect measurements on epitaxial SmNiO3 thin films and implications for antiferromagnetism
Sieu D. Ha, R. Jaramillo, D. M. Silevitch +4
The rare-earth nickelates (RNiO3) exhibit interesting phenomena such as unusual antiferromagnetic order at wavevector q = (1/2, 0, 1/2) and a tunable insulator-metal transition tha…
