Spintronics aims at developing a new generation of electronic materials for consumer products based on electron spin rather than on electron charge. Its main objective is the fabrication of new devices based on semiconductor materials with magnetic behavior (so called diluted magnetic semiconductors). These devices combine the manipulation of electrons as classically known in semiconductor devi...

In this review paper, a critical analysis was carried out to investigate the effect of cathodic potential, bath temperature, time and nature of substrates on the ZnO thin films synthesized by electrodeposition technique. XRD patterns of the various deposited films were studied to examine the structural characteristics of the Nanostructured ZnO thin films. From the XRD patterns of the different ...

Cuprous oxide (Cu2O) thin films were prepared by using electrodeposition technique at different applied potentials (-0.1, -0.3, -0.5, -0.7, and -0.9 V) and were annealed in vacuum at a temperature of 100°C for 1 h. Microstructure and optical properties of these films have been investigated by X-ray diffractometer (XRD), field-emission scanning electron microscope (SEM), UV-visible (vis) spectro...

A first-principles model of the electrochemical double layer is applied to study surface energies and surface coverage under realistic electrochemical conditions and to determine the equilibrium shape of metal nanoparticles as a function of applied potential. The potential bias is directly controlled by adding electronic charge to the system, while total energy calculations and thermodynamic re...

This paper is the first to report a large-scale directcurrent electrodeposition of columnar nanotwinned copper within through silicon via (TSV) with a high aspect ratio (~4). With this newly developed technique, void-free nanotwinned copper array could be fabricated in low current density (30 mA/cm²) and convection conditions (300 rpm), which are the preconditions for copper deposition with a u...

The waveform was designed to deposit a metal thickness equivalent during cathodic pulse and strip half anodic pulse. shape modified study its effect codeposition by changing current density p...

Abstract Electrodeposition of nickel from slightly acidic gluconate solutions containing chloride or/and sulfate ions was investigated. Electrochemical measurements correlated with bath speciations showed complex and complexes as crucial species affecting cathodic reactions in a potential range up to ?1.3V. At more negative potentials, deposition governed by release cation nickel-gluconate comp...
