Electric field and strain-induced band-gap engineering and manipulation of the Rashba spin splitting in Janus van der Waals heterostructures (2022)
Journal Article
Patel, S., Dey, U., Adhikari, N. P., & Taraphder, A. (2022). Electric field and strain-induced band-gap engineering and manipulation of the Rashba spin splitting in Janus van der Waals heterostructures. Physical Review B, 106(3), Article 035125. https://doi.org/10.1103/physrevb.106.035125

The compositional as well as structural asymmetries in Janus transition metal dichalcogenides (J-TMDs) and their van der Waals heterostructures (vdW HSs) induce an intrinsic Rashba spin splitting. We investigate the variation of band gaps and the Ras...

Multiple low-energy excitons and optical response of d0 double perovskite Ba2ScTaO6 (2022)
Journal Article
Himanshu, A., Kumar, S., Dey, U., & Ray, R. (2022). Multiple low-energy excitons and optical response of d0 double perovskite Ba2ScTaO6. Physica B: Condensed Matter, 637, Article 413856. https://doi.org/10.1016/j.physb.2022.413856

Large bandgap insulators are considered promising for applications such as photocatalysts, dielectric resonators and interference lters. Based on synchrotron X-ray diraction, diuse re ectance measurement and density functional theory, we report the c...
