Effective tight-binding Hamiltonian for the low-energy electronic structure of the Cu-doped lead apatite and the parent compound
Mayank Gupta, S. Satpathy, B. R. K. Nanda
We examine the origin of the formation of narrow bands in LK-99 (PbCu(PO)O) and the parent compound without the Cu doping using density functional theory calculations…
Electron confinement in chain-doped TMDs: A platform for spin-orbit coupled 1D physics
Mayank Gupta, Amit Chauhan, S. Satpathy +1
The state-of-the-art defect engineering techniques have paved the way to realize novel quantum phases out of pristine materials. Here, through density-functional calculations and m…
Spin Texture as Polarization Fingerprint of Halide Perovskites
Mayank Gupta, B. R. K. Nanda
Halide perovskites are perceived to be the promising class of materials for optoelectronics, spinorbitronics and topological electronics due to presence of strong spin-orbit coupli…
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…
Pressure and Inversion Symmetry Breaking Field Driven First Order Phase Transition and Formation of Dirac Circle in Perovskites
