The cat's lateral posterior-pulvinar complex (LP-pulvinar) contains three main representations of the visual field. The lateral part of the LP nucleus (LPl or striate-recipient zone) is the only region of these extrageniculate nuclei which receives afferents from the primary visual cortex. We investigated the contribution of area 17 to the response(More)
Iron pyrite (FeS(2)) is a naturally abundant and nontoxic photovoltaic material that can potentially make devices as efficient as silicon-based ones; however existing iron pyrite photovoltaic devices contain thermodynamically unstable FeS(2) film surfaces that lead to low open circuit voltages. We report the rational synthesis of phase pure, highly(More)
Iron pyrite is a promising photovoltaic material. The band gap broadening of FeS 2 nanocrystals by 0.1 eV was realized by zinc alloying. A more than fi ve-fold increase of the photoresponse with zinc alloying was observed in the zinc alloyed iron pyrite devices. Iron pyrite (FeS 2) is one of the most promising photovoltaic materials with high natural(More)
