Field emission is one of the main applications of one-dimensional (1D) nanostructures with enhanced local electric field due to their sharp tips and high aspect ratio. One of such 1D field emitters is CuO nanowires. CuO nanowires are capable of achieving a high field emission current density at relatively low field exhibiting uniform field emission distribution. The enhancement of field emission property...
Supported copper oxide nanosystems (CuxO, x = 1,2) were synthesized by chemical vapor deposition (CVD) on Al2O3 substrates. Structural and morphological characterization showed an evolution from polycrystalline Cu2O granular films to CuO samples with an entangled quasi 1-D morphology upon increasing the growth temperature from 350 to 550??C. For the first time, CVD copper oxide nanosystems were investigated...
The magneto-transport properties of ferromagnetic based multilayers are dependent on the film thickness, the surface roughness, the nature of the interlayer and pining layer used for exchange biasing. We investigate how the nature of the spacer-layer affects the magnetoresistance and Hall effect properties of the magnetic multilayers. The effective thicknesses of the oxide layers were estimated by...
Nickel-Iron (Ni-Fe) thin films were pulse-electrodeposited on copper (Cu) substrates under galvanostatic mode in the presence/absence of an ultrasonic field. The as-prepared thin films were characterized by X-Ray Diffractometer (XRD) and Scanning Electron Microscopy (SEM). The XRD results confirmed the deposition of NiFe on Cu substrates and the crystallite size calculated from Scherrerpsilas formula...
