Large-area CuO nanowires have been synthesized by thermal oxidation of porous copper film in static air. The effect of the thermal oxidation temperature and duration are found to influence the growth of CuO nanowires significantly. With an optimized condition, the porous copper film is converted into pure CuO. The application of the as-synthesized CuO nanowires in nanoenergetic materials is also studied...
Thermal oxidation of copper is a simple and scalable method to produce copper oxide nanowires. We report for the first time the formation of nanowires on copper powder during thermal oxidation and the resulting nanowire coverage that is dependent on initial particle size. Systematic thermogravimetric analysis (TGA) and in-situ x-ray diffraction (XRD) studies of thermal oxidation of particles of different...
Transconductance (gm) enhancement in n-type and p-type nanowire field-effect-transistors (nwFETs) is demonstrated by introducing controlled tensile strain into channel regions by pattern dependant oxidation (PADOX). Values of gm are enhanced relative to control devices by a factor of 1.5 in p-nwFETs and 3.0 in n-nwFETs. Strain distributions calculated by a three-dimensional molecular dynamics simulation...
