Signature of enhanced spin-orbit interaction in the magnetoresistance of LaTiO/SrTiO interfaces on -doping
Shubhankar Das, Z. Hossain, R. C. Budhani
We present a study of modulation of spin-orbit interaction (SOI) at the interface of LaTiO/SrTiO by -doping with an iso-structural ferromagnetic perovskite LaCoO. Th…
Defect-induced photoluminescence of strontium titanate and its modulation by electrostatic gating
Dushyant Kumar, R. C. Budhani
The photoluminescence (PL) spectra of Ar-ion irradiated single crystals of SrTiO3 (STO) excited by the 325 nm line of a He-Cd laser are compared with those of pristine crystals, ep…
Dynamics of photo-generated non-equilibrium electronic states in Ar ion irradiated SrTiO
Dushyant Kumar, Z. Hossain, R. C. Budhani
A metallic surface is realized on stoichiometric and insulating (100) SrTiO by Ar - ion irradiation. The sheet carrier density and Hall mobility of the layer are $4.0…
Observation of transient superconductivity at the LaAlO/SrTiO interface
Gopi Nath Daptary, Shelender Kumar, Pramod Kumar +6
We report the observation of a magnetic field assisted transient superconducting state in the two dimensional electron gas existing at the interface of LaAlO/SrTiO heterost…
Enhanced spin-orbit coupling and charge carrier density suppression in LaAl1-xCrxO3/SrTiO3 heterointerfaces
Pramod Kumar, Anjana Dogra, P. P. S. Bhadauria +3
We report a gradual suppression of the two-dimensional electron gas (2DEG) at the LaAlO3/SrTiO3 interface on substitution of chromium at the Al sites. The sheet carrier density at…
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…
