Morphology dependent surface properties of nanostructured GaN films grown by molecular beam epitaxy
Abhijit Chatterjee, S. P. Swathi, S. M. Shivaprasad
The effect of film morphology on its surface chemistry and band structure has been analyzed for gallium nitride epitaxial films grown by molecular beam epitaxy. The film morphology…
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…
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…
GaN Nanowall Network: A new possible route to obtain efficient p-GaN and enhanced light extraction
Sanjay Kumar Nayak, Mukul Gupta, S. M. Shivaprasad
We demonstrate that GaN formed in a Nanowall Network (NwN) morphology can overcome fundamental limitations in optoelectronic devices, and enable high light extraction and effective…
