Evidence for trivial Berry phase and absence of chiral anomaly in semimetal NbP
Sudesh, P. Kumar, P. Neha +3
We report a detailed magneto-transport study in single crystals of NbP. High quality crystals were grown by vapour transport method. An exceptionally large magnetoresistance is con…
Density driven fluctuations in a two-dimensional superconductor
S. Hurand, J. Biscaras, N. Bergeal +11
In the vicinity of a phase transition, the order parameter starts fluctuating before vanishing at the critical point. The fluctuation regime, i.e. the way the ordered phase disappe…
Magnetothermopower of -doped LaTiO/SrTiO interfaces in the Kondo regime
Shubhankar Das, P. C. Joshi, A. Rastogi +2
Measurements of magneto-thermopower (S(H, T)) of interfacial delta doped LaTiO/SrTiO (LTO/STO) heterostructure by an iso-structural antiferromagnetic perovskite LaCrO a…
Enhanced spin-orbit interaction and Kondo scattering in -doped LaTiO/SrTiO interfaces
Shubhankar Das, A. Rastogi, Lijun Wu +4
We present a study of delta () doping at LaTiO/SrTiO (LTO/STO) interface with iso-structural antiferromagnetic perovskite LaCrO (LCO) that dramatically alters the pr…
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…
Multi-band superconductivity and nanoscale inhomogeneity at oxide interfaces
S. Caprara, J. Biscaras, N. Bergeal +7
The two-dimensional electron gas at the LaTiO3/SrTiO3 or LaAlO3/SrTiO3 oxide interfaces becomes superconducting when the carrier density is tuned by gating. The measured resistance…
Multiple Quantum Phase Transitions at the superconducting LaTiO3/SrTiO3 interface
J. Biscaras, N. Bergeal, S. Hurand +6
We study the magnetic field driven Quantum Phase Transition (QPT) in electrostatically gated superconducting LaTiO3/SrTiO3 interfaces. Through finite size scaling analysis, we show…
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…
Irreversibility and time relaxation in electrostatic doping of oxide interfaces
J. Biscaras, S. Hurand, C. Feuillet-Palma +8
Two-dimensional electron gas (2DEG) confined in quantum wells at insulating oxide interfaces have attracted much attention as their electronic properties display a rich physics wit…
Two-dimensional superconductivity induced by high-mobility carrier doping in LaTiO3/SrTiO3 hetero-structures
J. Biscaras, N. Bergeal, S. Hurand +6
In this letter, we show that a superconducting two-dimensional electron gas is formed at the LaTiO3/SrTiO3 interface whose transition temperature can be modulated by a back-gate vo…
