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…
Enhanced radial growth of Mg doped GaN nanorods: A combined experiment and first-principles based analysis
Sanjay Nayak, Rajendra Kumar, Nagaraja KK +1
We discuss the microstructural origin of enhanced radial growth in magnesium (Mg) doped gallium nitride (GaN) nanorods (NRs) using electron microscopy and \textit{first-principles}…
On the origin of Blue Luminescence in Mg doped GaN
Sanjay Nayak, Mukul Gupta, Umesh V. Waghmare +1
We uncover the origin of blue luminescence (BL) peak in Mg doped GaN thin film using a combination of experimental X-ray absorption near edge spectroscopy (XANES), first-principles…
Edge enhanced growth induced shape transition in the formation of GaN Nanowall Network
Sanjay Nayak, Rajendra Kumar, S. M. Shivaprasad
We address the mechanism of early stages of growth and shape transition of the unique nanowall network (NwN) nanostructure of GaN by experimentally monitoring its controlled growth…
