Frequency dependence of the magnetoimpedance in amorphous CoP electrodeposited layers
Magnetic properties and changes of impedance upon external field ~MI! are studied in amorphous CoP magnetic layers obtained by galvanostatic electrodeposition over cylindrical Cu substrates. The magnetic layer thickness is controlled by deposition time and varies between 3 and 7 mm. Due to the columnar growth of Co, thicker layers have stronger perpendicular radial anisotropy. The field and fre...
متن کاملSilicon nanowire array photelectrochemical cells.
The development of efficient but inexpensive solar cells is an important current challenge. Semiconductor nanowires provide new opportunities for addressing the cost and efficiency issues of conventional photovoltaic (PV) and photoelectrochemical (PEC) cells. Recent studies of semiconductor nanowire growth1-3 show that it is relatively easy to make arrays of vertically oriented single crystals,...
متن کاملDendritic nanowire ultraviolet laser array.
Self-organized dendritic crystal growth is explored to assemble uniform semiconductor nanowires into highly ordered one-dimensional microscale arrays that resemble comb structures. The individual ZnO nanowires have uniform diameters ranging from 10 to 300 nm. They are evenly spaced on a stem with a regular periodicity of 0.1-2 micrometer. Under optical excitation, each individual ZnO nanowire s...
متن کاملPhonon spectroscopy in a Bi2Te3 nanowire array.
The lattice dynamics in an array of 56 nm diameter Bi2Te3 nanowires embedded in a self-ordered amorphous alumina membrane were investigated microscopically using (125)Te nuclear inelastic scattering. The element specific density of phonon states is measured on nanowires in two perpendicular orientations and the speed of sound is extracted. Combined high energy synchrotron radiation diffraction ...
متن کاملMagnetoresistive effects in planar NiFe nanoconstrictions
This study focuses on domain wall resistance in Ni80Fe20 nanowires containing narrow constrictions down to 15 nm in width. Distinct differences in the magnetoresistance curves were found to depend on the constriction size. Wider constrictions are dominated by the overall anisotropic magnetoresistance of the structure, while constrictions narrower than ;40 nm exhibit an additional distinct contr...
