Light-matter interaction of single semiconducting AlGaN nanowire and noble metal Au nanoparticle in the sub-diffraction limit
A. K. Sivadasan, Kishore K. Madapu, Sandip Dhara
The near field scanning optical microscopy (NSOM) is not only a tool for imaging of sub-diffraction limited objects but also a prominent characteristic tool for understanding the i…
Piezoelectric Domains in the AlGaN Hexagonal Microrods: Effect of Crystal Orientations
A. K. Sivadasan, G. Mangamma, S. Bera +2
Presently, the piezoelectric materials are finding tremendous applications in the micro-mechanical actuators, sensors and self-powered devices. In this context, the studies pertain…
Polarized Raman and photoluminescence studies of a sub-micron sized hexagonal AlGaN crystallite for structural and optical properties
A. K. Sivadasan, S. Dhara
The polarized Raman spectroscopy is capable of giving confirmation regarding the crystalline phase as well as the crystallographic orientation of the sample. In this context, apart…
Optically confined polarized resonance Raman studies in identifying crystalline orientation of sub-diffraction limited AlGaN nanostructure
A. K. Sivadasan, Avinash Patsha, Sandip Dhara
An optical characterization tool of Raman spectroscopy with extremely weak scattering cross section tool is not popular to analyze scattered signal from a single nanostructure in t…
