Non-monotonic size dependence of the elastic modulus of nanocrystalline ZnO embedded in a nanocrystalline silver matrix
Vinod Panchal, Shankar Ghosh, Smita Gohil +2
We present the first high pressure Raman study on nanocrystalline ZnO films with different average crystallite sizes. The problem of low Raman signals from nano sized particles was…
Competing effects of surface phonon softening and quantum size effects on the superconducting properties of nanostructured Pb
Sangita Bose, Charudatta Galande, S. P. Chockalingam +3
The superconducting transition temperature (TC) in nanostructured Pb remains nearly constant as the particle size is reduced from 65 to 7nm, below which size the superconductivity…
Upper critical field in nanostructured Nb: Competing effects of the reduction in density of states and the mean free path
Sangita Bose, Pratap Raychaudhuri, Rajarshi Banerjee +1
We show that the upper critical field in nanometer-sized Nb particles is governed by the changes in the effective Ginzburg-Landau coherence length occurring due to two competing fa…
Size induced metal insulator transition in nanostructured Niobium thin films: Intragranular and intergranular contributions
Sangita Bose, Rajarshi Banerjee, Arda Genc +3
With a reduction in the average grain size in nanostructured films of elemental Nb, we observe a systematic crossover from metallic to weakly-insulating behavior. An analysis of th…
Nanostructures and enhanced absorption in intense laser interaction with matter: effect of laser prepulses
P. P. Rajeev, S. Kahaly, S. Bose +4
Hard x-ray emission (20 - 200 keV) from plasmas produced by intense laser pulses on nanoparticle coated targets is compared with that from optically polished targets. The yield enh…
Size-enhanced, coherent photoluminescence from CdS-ZnO nanocomposite thin film
Pushan Ayyub, Parinda Vasa, Praveen Taneja +2
We show that the photoluminescence emitted from a dense, two-component ensemble of quantum dots is significantly higher than that from quantum dots of either of the two pure system…
