Spontaneous ferromagnetism and finite surface energy gap in the topological insulator BiSe from surface Bi$_\rm{Se}$ antisite defects
Suhas Nahas, Biplab Sanyal, Annica M. Black-Schaffer
We perform ab-initio calculations on Bi antisite defects in the surface of BiSe, finding strong low-energy defect resonances with a spontaneous ferromagnetism…

Electronic structure and transport in amorphous metal oxide and amorphous metal oxy-nitride semiconductors
Juhi Srivastava, Suhas Nahas, Somnath Bhowmick +1
Recently amorphous oxide semiconductors (AOS) have gained commercial interest due to their low-temperature processability, high mobility and areal uniformity for display backplanes…

First Principles Prediction of Amorphous Phases Using Evolutionary Algorithms
Suhas Nahas, Anshu Gaur, Somnath Bhowmick
We discuss the efficacy of evolutionary method for the purpose of structural analysis of amorphous solids. At present ab initio molecular dynamics (MD) based melt-quench technique…
