High fuel efficiency is needed to minimize the quantities of radioisotopic or nuclear fuels in the systems, to maximize power to mass ratios, and to minimize housing requirements. Even though more ยป RTG's have proven their reliability and have respectable power to mass ratios, it is desirable to attain efficiencies of at least 25% in typical applications. We present X-ray photoelectron spectroscopy (XPS) and X-ray photoelectron diffraction (XPD) investigations of CuO thin films electrochemically deposited on an Au(001) single-crystal surface from a solution containing chiral tartaric acid (TA). It has been theoretically shown, and to some extent experimentally demonstrated, that RECS, capacitive DEC systems, and possibly BPC's are all potentially capable of efficiencies well above the 9% maximum efficiency demonstrated to date in RTG's customized for deep space probe applications. There have been theoretical evaluations of, and some experimental testing of, several types of nuclear batteries including Radioisotope Energy Conversion Systems (RECS), Direct Energy Conversion (DEC) systems, and Betavoltaic Power Cells (BPC's). In this paper we compare the potential performance capabilities of several types of nuclear batteries to the Radioisotope Thermocouple Generators (RTG's) currently in use. MPECVD was then used, as described further below, to generate C atoms that diffuse through the Cu(111) film to the Cu(111)Al 2 O 3 (0001) interface such that a single-crystal graphene grows. A continuous-wave laser diode with a micrometer-scale chevron-shaped beam profilemicro-chevron laser beam (-CLB)was used to form single-crystal Cu2O strips crystallized in CuO thin films. Our study opens up a pathway toward developing bi-functional ferroelectric devices with simultaneously high energy storage density and high photovoltaic performance. Epitaxial electrodeposition of chiral CuO films from copper(II) complexes of malic acid on Cu(111) and Cu(110) single crystals Rakesh V. The formation of the giant graphene single crystals eliminates the grain boundary scattering to ensure excellent device-to-device uniformity and remarkable electronic properties with the expected. The growth mechanism to obtain a dense and uniformly distributed (in the axial direction in a tubular reactor) film was investigated. The maximum power conversion efficiency was enhanced one order of magnitude than that of polycrystalline PZT film reported elsewhere. CuO x films were deposited on silica substrates by the chemical vapor deposition (CVD) method, using CuI and O 2 as source gases at low pressure in a tubular reactor.
