    "abstract": "We present the effect of a nanostructured surface on the emission of ions and\nelectrons from intense (5-36 Petwatt per sq.cm) femtosecond laser produced\nplasmas. Electrons from optically polished copper targets coated with copper\nnanoparticles (CuNP) are observed to be hotter than those from uncoated\npolished targets. A nearly two-fold enhancement is observed for ions in the\nrange 14-74 keV, while ion yield decreases by a factor of 2 in the 74-2000 keV\nrange. The total ion yields measured using a large area Faraday cup are more\nfrom CuNP targets than those from polished Cu targets, indicating increased ion\nbeam divergence due to surface modulations.",
