The bonding configuration in a partially relaxed pseudomorphic epilayer of SiGe: evidence of the BC-8 phase of silicon
M Pandey,Samit K. Ray,P Selvam +2 more
TL;DR: In this paper, the bonding configuration of a silicon host lattice in a carbon-induced partially relaxed pseudomorphic epilayer of SiGe is studied using x-ray photoelectron spectroscopy, high-resolution XRD and Raman spectroscopic techniques.
Proceedings ArticleDOI
Effect of annealing on photoluminescence property of nano particle composite ZnO films
TL;DR: The effect of annealing temperature on the structural and photoluminescence properties of nanocrystalline ZnO films deposited by sol-gel process has been investigated in this paper.
Proceedings ArticleDOI
Broadband absorption in Au nanoparticle-decorated chlorophyll b for biophotonic applications
Hasmat Mondal,Poulomi Chakrabarty,Arijit Sarkar,Gaurab Gangopadhyay,Rabaya Basori,Samit K. Ray +5 more
TL;DR: In this article, a broadband absorption of gold nanoparticle-decorated chlorophyll b was extracted from spinach, and a broad absorption spectrum ranging from 315 nm to 1025 nm was obtained.
Journal ArticleDOI
Excitation power-independent photoluminescence of inverted quantum hut structures embedded in SiGe superlattice
TL;DR: In this paper, the photoluminescence of MBE-grown SiGe superlattice structures having inverted quantum huts of Ge formed below Ge-on-Si interfaces was studied.
Journal Article
Synthesis and characterization of nickel titanium melt-spun ribbon for micro-actuator device application
Debashis Panda,M. Ranot,Kaustuv Das,D. Bhattacharya,Anindya Sundar Dhar,M. Chakraborty,Samit K. Ray +6 more
TL;DR: In this paper, the phase transformation of the ribbons has been studied using resistivity measurement as a function of temperature, and the structure, composition and surface topography of melt-spun ribbons are studied using scanning electron microscopy, energy dispersive X-ray measurements and atomic force microscopy.
