Low Thermal Budget NiSi Films on SiGe Alloys
Samit K. Ray,Samit K. Ray,Thomas N. Adam,G. S. Kar,G. S. Kar,Charles P. Swann,James Kolodzey +6 more
TL;DR: Nickel silicides were formed on Si (100) substrates and CVD grown Si0.9Ge0.1/Si layers by low thermal budget annealing of evaporated Ni films to evaluate their utility for ultra shallow junctions.
Journal ArticleDOI
Synthesis of Cu nanoparticles in a chitosan entrapped copolymer matrix for photocatalytic reduction of textile dye and column adsorption of heavy metal ions from water
Bidyut Kumar Bhangi,Samit K. Ray +1 more
TL;DR: In this paper , a polymer metal nano-composites (PMNC) was synthesized by integrating different weight percentage of chitosan (CS), N,N′-methylenebisacrylamide (MBA) crosslinked poly(acrylic acid-co-hydroxyethyl methacrylate) copolymer and Cu nanoparticles (CuNPs).
Journal ArticleDOI
Structural and electrical characteristics of the interfacial layer of ultrathin ZrO2 films on partially strain compensated Si0.69Ge0.3C0.01 layers
Rajat Mahapatra,Siddheswar Maikap,Je-Hun Lee,G. S. Kar,Anirban Dhar,Doh-Y. Kim,D. Bhattacharya,Samit K. Ray +7 more
TL;DR: In this article, the structural characteristics of ZrO2 films along with the interfacial layers deposited on partially strain compensated Si0.69Ge0.3C0.01/Si heterostructure have been investigated using x-ray diffraction (XRD), high resolution transmission electron microscopy (TEM), time-of-flight secondary ion mass spectroscopy (SIMS), and X-ray photoelectron spectrograph (XPS) measurements.
Journal ArticleDOI
Efficiency Enhancement of Solar Cell by Introduction of Cerium Oxide along with Silicon Nitride
TL;DR: In this article, the authors have carried out the comparative simulations study of n type c-Si solar cells with SiNx and SiNix+CeO2 layers separately by PC1D simulation software.
Journal ArticleDOI
White-light emission by phonon assisted coherent mixing of excitons in Au8-CdS hybrid nanorods.
S. Rath,O. Halder,A. Pradhani,Biswarup Satpati,Achyut Maity,Tapas Kumar Chini,Narendar Gogurla,Samit K. Ray +7 more
TL;DR: Gold cluster (Au8) coated CdS hybrid nanorods (HNRs), synthesized using a sonication assisted assembly route, exhibit phonon assisted coherent mixing of excitons, effecting enhancement of exciton-phonon (e-p) interactions.
