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…

Second Neighbor Electron Hopping and Pressure Induced Topological Quantum Phase Transition in Insulating Cubic Perovskites
Ravi Kashikar, Bramhachari Khamari, B. R. K. Nanda
Perovskite structure is one of the five symmetry families suitable for exhibiting topological insulator phase. However, none of the halides and oxides stabilizing in this structure…
