Signatures of non-trivial band topology in LaAs/LaBi heterostructure
Payal Wadhwa, T. J. Dhilip Kumar, Alok Shukla +1
In this article, we investigate non-trivial topological features in a heterostructure of extreme magnetoresistance (XMR) materials LaAs and LaBi using density functional theory (DF…
First principles investigation of topological phase in XMR material TmSb under hydrostatic pressure
Payal Wadhwa, Shailesh Kumar, Alok Shukla +1
In this article, we report emergence of topological phase in XMR material TmSb under hydrostatic pressure using first principles calculations. We find that TmSb, a topologically tr…
Studies of non-trivial band topology and electron-hole compensation in YSb
Payal Wadhwa, Shailesh Kumar, Alok Shukla +1
In this article, we study non-trivial topological phase and electron-hole compensation in extremely large magnetoresistance (XMR) material YSb under hydrostatic pressure using firs…
Band Gap tunability in One-dimensional system
Payal Wadhwa, Shailesh Kumar, T. J. Dhilip Kumar +2
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 bandga…
Effect of edge defects on band structure of zigzag graphene nanoribbons
Payal Wadhwa, Shailesh Kumar, T. J. Dhilip Kumar +2
In this article, we report band structure studies of zigzag graphene nanoribbons (ZGNRs) on introducing defects (sp_3 hybridized carbon atoms) in different concentrations at edges…
