Microscopic Origin of Structural Disorder in -NbN: Correlation of Superconductivity and Electronic Structure
Shailesh Kalal, Sanjay Nayak, Akhil Tayal +3
Rock-salt type niobium nitride (-NbN) is a well-known superconductor having superconducting transition temperature (Tc) 18\,K and a large superconducting gap …
Gallium-Boron-Phosphide (GaBP): A New III-V Semiconductor for photovoltaics
Upendra Kumar, Sanjay Nayak, Soubhik Chakrabarty +2
Using machine learning (ML) approach, we unearthed a new III-V semiconducting material having an optimal bandgap for high efficient photovoltaics with the chemical composition of G…
Error Minimization in Predicting Accurate Adsorption Energies Using Machine Learning
Sanjay Nayak, Satadeep Bhattacharjee, Jung-Hae Choi +1
Finding the "ideal" catalyst is a matter of great interest in the communities of chemists and material scientists, partly because of its wide spectrum of industrial applications. I…
Spectroscopic signatures of native charge compensation in Mg doped GaN Nanorods
Rajendra Kumar, Sanjay Nayak, S. M. Shivaprasad
We study the native charge compensation effect in Mg doped GaN nanorods (NRs), grown by Plasma Assisted Molecular Beam Epitaxy (PAMBE), using Raman, photoluminescence (PL) and X-ra…
Vacancy defect in bulk and at (100) surface of GaN: A combined first-principles theoretical and experimental analysis
Sanjay Nayak, Mit H. Naik, Manish Jain +2
We determine atomic and electronic structure, formation energy, stability and magnetic properties of native point defects, such as Gallium (Ga) and Nitrogen (N) vacancies in bulk a…
