Electronic Structure and Carrier Mobilities of Twisted Graphene Helix
Rajesh Thakur, P. K. Ahluwalia, Ashok Kumar +2
We have investigated the effect of twisting on electronic band structure, effective mass and carrier mobilities of three prototypes of AGNRs (N=6, 7 & 8) using Density functional t…
Twisted Helical shaped Graphene Nano-Ribbons: Role of Symmetries and Passivation
Rajesh Thakur, P. K. Ahluwalia, Ashok Kumar +2
The Hydrogen and Fluorine planar armchairs graphene nanoribbons (H and F AGNRs), subjected to twist deformation within fixed periodic boundary conditions, eventually morph to a hel…
Tin Titanate: the hunt for a new ferroelectric perovskite
J. Gardner, Atul Thakre, Ashok Kumar +1
We review all the published literature and show that there is no experimental evidence for homogeneous tin titanate SnTiO3 in bulk or thin-film form. Instead a combination of unrel…
Two Dimensional Allotropes of Arsenene with Wide Range of High and Anisotropic Carrier Mobility
Pooja Jamdagni, Anil Thakur, Ashok Kumar +2
Considering the rapid development of experimental techniques for fabricating 2D materials in recent years, various monolayers are expected to be experimentally realized in the near…
Monolayer, Bilayer and Heterostructures of Green Phosphorene for Water Splitting and Photovoltaics
Sumandeep Kaur, Ashok Kumar, Sunita Srivastava +2
We report the results of density functional theory (DFT) based calculations on monolayer and bilayer green phosphorene and their heterostructures with MoSe2. Both monolayer and bil…
Stability and Carrier Transport Properties of Phosphorene Based Polymorphic Nanoribbons
Sumandeep Kaur, Ashok Kumar, Sunita Srivastava +2
A few-layer black phosphorene has recently gained significant interest in the scientific community. In this paper, we consider several polymorphs of phosphorene nanoribbons (PNRs)…
