Chiral orbital/spin textures and Edelstein effects in monolayer Janus TMDs
Pratik Sahu, Sashi Satpathy, Birabar Ranjit Kumar Nanda
We investigate the orbital and spin Edelstein effect(OEE and SEE) in two-dimensional Janus transition metal dichalcogenides (TMDs) of the form MXX $(M = Mo,\ W,\ Nb;\ X/X^…
Unique Superconducting State in the Cuprate Member BaCuO
Priyo Adhikary, Mayank Gupta, Amit Chauhan +3
Recent discovery of superconductivity at a transition temperature of K in the doped layered compound BaCuO for has generated a lot of interest. Experi…
Quantum Mechanical Process of Carbonate Complex Formation and Large Scale Anisotropy in the Adsorption Energy of CO on Anatase TiO (001) Surface
Shashi B. Mishra, Aditya Choudhary, Somnath C. Roy +1
Adsorption of CO on a semiconductor surface is a prerequisite for its photocatalytic reduction. Owing to superior photocorrosion resistance, nontoxicity and suitable band edge…
