Feeble Metallicity and Robust Semiconducting Regime in Structurally Sensitive Ba(Pb, Sn)O Alloys
Ravi Kashikar, B. R. K. Nanda
Density functional calculations are carried out to study the symmetry and substitution-driven electronic phase transition in BaPbSnO. Two end members BaSnO and…
A Generic Slater-Koster Description of the Electronic Structure of Centrosymmetric Halide Perovskites
Ravi Kashikar, Mayank Gupta, B. R. K. Nanda
The halide perovskites have truly emerged as efficient optoelectronic materials and show the promise of exhibiting nontrivial topological phases. Since the bandgap is the determini…
Electronic Structure of Graphene/TiO Interface: Design and Functional Perspectives
Shashi B. Mishra, Somnath C. Roy, B. R. K. Nanda
We propose the design of low strained and energetically favourable mono and bilayer graphene overlayer on anatase TiO (001) surface and examined the electronic structure of the…
Pressure and Inversion Symmetry Breaking Field Driven First Order Phase Transition and Formation of Dirac Circle in Perovskites
Ashish Kore, Ravi Kashikar, Mayank Gupta +2
Through model Hamiltonian studies and first-principle electronic structure calculations, we have examined the effect of inversion symmetry breaking (ISB) field and hydrostatic pres…
Defining the Topological Influencers and Predictive Principles to Engineer Band Structure of Halide Perovskites
Ravi Kashikar, Mayank Gupta, B. R. K. Nanda
Complex quantum coupling phenomena of halide perovskites are examined through ab-initio calculations and exact diagonalization of model Hamiltonians to formulate a set of fundament…
Shifting of Fermi Level and Realization of Topological Insulating Phase in the Oxyfluoride BaBiOF
Bramhachari Khamari, B. R. K Nanda
The disadvantage of BaBiO of not being a topological insulator despite having symmetry protected Dirac state is overcome by shifting the Fermi level (E) via fluorination. T…
