Evidence of Slater-type mechanism as origin of insulating state in Sr2IrO4
Vijeta Singh, J. J. Pulikkotil
For iridates with large spatially extended 5d orbitals, it may be anticipated that distant neighbor interactions would play a crucial role in their ground state properties. From th…
Theoretical Study of Coulomb Correlations and Spin-Orbit Coupling in SrIrO3
Vijeta Singh, J. J. Pulikkotil
Given that energy scales associated with crystal field splitting, spin orbit coupling and coulomb correlations in iridates are comparable, hence leading to exotic properties, we in…
Cooperative effects of lattice and spin-orbit coupling on the electronic structure of orthorhombic SrIrO3
Vijeta Singh, J. J. Pulikkotil
Orthorhombic SrIrO3 subjected to strain show tunable transport properties. With underlying symmetry remaining invariant, these properties are associated with IrO6 octahedral tiltin…
Enhanced persistent photoconductivity in -doped LaAlO/SrTiO heterostructures
A. Rastogi, J. J. Pulikkotil, R. C. Budhani
We report the effect of -doping at LaAlO/SrTiO interface with LaMnO monolayers on the photoconducting (PC) state. The PC is realized by exposing the samples to…
δ-doped LaAlO3-SrTiO3 interface: Electrical transport and characterization of the interface potential
A. Rastogi, S. Tiwari, J. J. Pulikkotil +3
Here we investigate LaAlO_3-SrTiO_3 heterostructure withδ-doping of the interface by LaMnO_3 at less than one monolayer. This doping strongly inhibits the formation of mobile elect…
Novel photo-conducting state and its perturbation by electrostatic fields in oxide-based two-dimensional electron gas
A. Rastogi, J. J. Pulikkotil, S. Auluck +2
The two-carrier transport model as proposed for the two-dimensional electron gas formed at the interfaces of oxide heterostructures is investigated by means of a combined perturbat…
