Large Electron Concentration Modulation using Capacitance Enhancement in SrTiO3/SmTiO3 FinFETs
Amit Verma, Kazuki Nomoto, Wan Sik Hwang +3
Solid-state modulation of 2-dimensional electron gases (2DEGs) with extreme (~3.3 x 1014 cm-2) densities corresponding to 1/2 electron per interface unit cell at complex oxide hete…
Carrier density independent scattering rate in SrTiO3-based electron liquids
Evgeny Mikheev, Santosh Raghavan, Jack Y. Zhang +4
We examine the carrier density dependence of the scattering rate in two- and three-dimensional electron liquids in SrTiO3 in the regime where it scales with T^n (T is the temperatu…
Ferroelectric Transition in Compressively Strained SrTiO3 Thin Films
Amit Verma, Santosh Raghavan, Susanne Stemmer +1
We report the temperature dependent capacitance-voltage characteristics of Pt/SrTiO3 Schottky diodes fabricated using compressively strained SrTiO3 thin films grown on (LaAlO3)0.3(…
Au-Gated SrTiO3 Field-Effect Transistors with Large Electron Concentration and Current Modulation
Amit Verma, Santosh Raghavan, Susanne Stemmer +1
We report the fabrication of low-leakage rectifying Pt and Au Schottky diodes and Au-gated metal-semiconductor field effect transistors (MESFETs) on n-type SrTiO3 thin films grown…
Correlation between metal-insulator transitions and structural distortions in high-electron-density SrTiO3 quantum wells
Jack Y. Zhang, Clayton A. Jackson, Ru Chen +4
The electrical and structural characteristics of SmTiO3/SrTiO3/SmTiO3 and GdTiO3/SrTiO3/GdTiO3 heterostructures are compared. Both types of structures contain narrow SrTiO3 quantum…
Subband structure of two-dimensional electron gases in SrTiO3
Santosh Raghavan, S. James Allen, Susanne Stemmer
Tunneling between two parallel, two-dimensional electron gases (2DEGs) in a complex oxide heterostructure containing a large, mobile electron density of ~ 3x10^14 cm^-2 is used to…
Magnetism and local structure in low-dimensional, Mott insulating GdTiO3
Jack Y. Zhang, Clayton A. Jackson, Santosh Raghavan +2
Cation displacements, oxygen octahedral tilts, and magnetism of epitaxial, ferrimagnetic, insulating GdTiO3 films sandwiched between cubic SrTiO3 layers are studied using scanning…
