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…

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…

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…
