Doping a Bad Metal: Origin of Suppression of Metal-Insulator Transition in Non-Stoichiometric VO
P. Ganesh, Frank Lechermann, Ilkka Kylanpaa +3
Rutile () phase VO is a quintessential example of a strongly correlated bad-metal, which undergoes a metal-insulator transition (MIT) concomitant with a structural transitio…
Anomalous dielectric response at intermixed oxide heterointerfaces
Valentino R. Cooper, Houlong L. Zhuang, Lipeng Zhang +3
Two-dimensional charge carrier accumulation at oxide heterointerfaces presents a paradigm shift for oxide electronics. Like a capacitor, interfacial charge buildup couples to an el…
Oxygen vacancy formation energies in PbTiO/SrTiO superlattice
Lipeng Zhang, Isaac Bredeson, Axiel Yaël Birenbaum +4
The defect stability in a prototypical perovskite oxide superlattice consisting of SrTiO and PbTiO (STO/PTO) is determined using first principles density functional theory…
