In-situ real-time evolution of intrinsic stresses and microstructure during growth of cathodic arc deposited (Al,Ti)N coatings
Sanjay Nayak, Tun-Wei Hsu, Lina Rogström +8
The residual stress plays a vital role in determination of the device performance that uses thin films coating and thus the accurate determination of stress and its optimization wi…
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…
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…
