Polarization-tailored Fano interference in plasmonic crystals: A Mueller matrix model of anisotropic Fano resonance
S. K. Ray, S. Chandel, A. K. Singh +4
We present a simple yet elegant Mueller matrix approach for controlling the Fano interference effect and engineering the resulting asymmetric spectral line shape in anisotropic opt…
Controlled defects in ZnO by low energy Ar irradiation
Soubhik Chattopadhyay, Sreetama Dutta, D. Jana +6
We report interesting observations in 1.2 MeV Ar8+ ion irradiated ZnO which, to the best of our knowledge, have not been published earlier and will be useful for the scientific com…
Broadband pump-probe study of biexcitons in chemically exfoliated layered WS
R. K. Chowdhury, S. Nandy, S. Bhattacharya +5
Strong light-matter interactions in layered transition metal dichalcogenides (TMDs) open up vivid possibilities for novel exciton-based devices. The optical properties of TMDs are…
Optical property modification of ZnO: Effect of 1.2 MeV Ar irradiation
Soubhik Chattopadhyay, Sreetama Dutta, Palash Pandit +7
We report a systematic study on 1.2 MeV Ar^8+ irradiated ZnO by x-ray diffraction (XRD), room temperature photoluminescence (PL) and ultraviolet-visible (UV-Vis) absorption measure…
Realization of biferroic properties in La0.6Sr0.4MnO3 0.7Pb(Mg0.33Nb0.67)O3 0.3(PbTiO3) epitaxial superlattices
Ayan Roy Chaudhuri, r. Ranjith, S. B. Krupanidhi +4
A set of symmetric and asymmetric superlattices with ferromagnetic La0.6Sr0.4MnO3 and ferroelectric 0.7Pb(Mg0.33Nb0.67)O3 0.3(PbTiO3) as the constituting layers were fabricated on…
