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…
Metal nanoplasmas as bright sources of hard x-ray pulses
P. P. Rajeev, P. Taneja, P. Ayyub +2
We demonstrate a 13-fold increase in hard x-ray bremsstrahlung (10 - 200 keV) emitted by a copper plasma created by 100 fs, 806 nm pulses at Wcm. This enha…
Spin polarized tunneling in the half-metallic ferromagnet La0.7Sr0.3MnO3: experiment and theory
P. Raychaudhuri, K. Sheshadri, P. Taneja +4
The magnetoresistance (MR) in polycrystalline colossal magnetoresistive compounds follows a behavior different from single crystals below the ferromagnetic transition temperature.…
Magnetic field dependent variable range hopping behaviour in resistivity at low temperatures in polycrystalline colossal magnetoresistive manganites: evidence of spin polarised tunnelling
P. Raychaudhuri, P. Taneja, S. Sarkar +3
It has been observed that the low temperature magnetoresistance behaviour in polycrystalline colossal magnetoresistive (CMR) manganites differ significantly from the single crystal…
