Journal ArticleDOI
Photosensitization of ZnO nanowires with CdSe quantum dots for photovoltaic devices
Kurtis S. Leschkies,R. Divakar,Joysurya Basu,Emil Enache-Pommer,Janice E. Boercker,C. Barry Carter,Uwe Kortshagen,David J. Norris,Eray S. Aydil +8 more
TL;DR: CdSe semiconductor nanocrystals and single-crystal ZnO nanowires are combined to demonstrate a new type of quantum-dot-sensitized nanowire solar cell that exhibited short-circuit currents ranging from 1 to 2 mA/cm2 and open-circuits voltages of 0.5-0.6 V when illuminated with 100 mW/ cm2 simulated AM1.5 spectrum.
Journal ArticleDOI

S. Saroja,Arup Dasgupta,R. Divakar,Sree Bhushan Raju,E. Mohandas,M. Vijayalakshmi,K. Bhanu Sankara Rao,Baldev Raj +7 more
TL;DR: In this article, the results on the physical metallurgy studies in 9Cr Oxide Dispersion Strengthened (ODS) and Reduced Activation Ferritic/Martensitic (RAFM) steels were presented.
Journal ArticleDOI
Influence of nitrogen flow rate on microstructural and nanomechanical properties of Zr-N thin films prepared by pulsed DC magnetron sputtering
Akash Singh,Parasuraman Kuppusami,Shabana Khan,C. Sudha,R. Thirumurugesan,R. Ramaseshan,R. Divakar,E. Mohandas,Sitaram Dash +8 more
TL;DR: In this paper, Zr-N thin films were deposited on Si (1/0/0) substrate by reactive sputtering using a pulsed DC magnetron sputtering technique and the chemical bonding characteristics of the films were analyzed by X-ray photoelectron spectroscopy.
Journal ArticleDOI

G. Balakrishnan,Chinnambedu Murugesan Raghavan,Chanchal Ghosh,R. Divakar,E. Mohandas,Jung-Il Song,S.I. Bae,Tae Gyu Kim +7 more
TL;DR: In this article, the structural, morphological and optical properties of the thin films were characterized by X-ray diffraction, Raman spectroscopy, high resolution transmission electron microscopy, atomic force microscopy (AFM), photoluminescence, and UV-visible spectrograms.
Journal ArticleDOI
Eu3+ doped gadolinium oxysulfide (Gd2O2S) nanostructures—synthesis and optical and electronic properties
Jagannathan Thirumalai,Rathinam Chandramohan,R. Divakar,E. Mohandas,M. Sekar,P. Parameswaran +5 more
TL;DR: Optical and photo-induced impedance measurements have been extended to the nanotubes in this report to identify the origin and nature of the electronic transitions observed in the visible region.
