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…
Honeycomb antiferromagnet with a triply degenerate dimer ground state
Rakesh Kumar, Dushyant Kumar, Brijesh Kumar
We present an antiferromagnetic quantum spin-1/2 model on honeycomb lattice. It has two parts, one of which is the usual nearest-neighbor Heisenberg model. The other part is a cert…
