  • Bandgap tunability in a one-dimensional system 
    Wadhwa, P.; Kumar, S.; Kumar, T. J. D.; Shukla, A.; Kumar, R. (2021-10-16)
    The ability to tune the gaps of direct bandgap materials has tremendous potential for applications in the fields of LEDs and solar cells. However, lack of reproducibility of bandgaps due to quantum confinement observed ...
  • Effect of edge defects on band structure of zigzag graphene nanoribbons 
    Wadhwa, P.; Kumar, S.; Kumar, T.J.D.; Shukla, A.; Kumar, R. (2018-10-09)
    In this article, we report band structure studies of zigzag graphene nanoribbons (ZGNRs) on introducing defects (sp3 hybridized carbon atoms) in different concentrations at edges by varying the ratio of sp3 to sp2 hybridized ...
  • First principles investigation of topological phase in XMR material TmSb under hydrostatic pressure 
    Wadhwa, P.; Kumar, S.; Shukla, A.; Kumar, R. (2021-08-30)
    In this article, we report emergence of topological phase in extremely large magnetoresistance (XMR) material TmSb under hydrostatic pressure using first principles calculations. We find that TmSb, a topologically trivial ...
  • Non-trivial band topology in Bi doped Lanthanum monopnictides (LaX; X = As and Sb) 
    Wadhwa, P.; Dhilip Kumar, T.J.; Shukla, A.; Kumar, R. (2022-12-10)
    In this study, we report first-principles investigation of non-trivial topological characteristics in Bi doped Lanthanum monopnictides, particularly LaAs and LaSb. For this, we varied the concentration of Bi atoms in 1 × ...
  • Signatures of non-trivial band topology in LaAs/LaBi heterostructure 
    Wadhwa, P.; Kumar, T. J. D.; Shukla, A.; Kumar, R. (2021-06-10)
    In this article, we investigate non-trivial topological features in a heterostructure of extreme magnetoresistance (XMR) materials LaAs and LaBi using density functional theory. The proposed heterostructure is found to ...
