Porous GaAs was prepared using electrochemical anodization technique of a cristalline GaAs wafer in hydrofluoridric (HF) acid based-solution at different manufacturing conditions. The physical properties of porous GaAs are mainly determined by the shape, diameter of pores, porosity, and the thickness of deposited porous layers. Depending on the etching parameters such as current density, HF con...

The technlque of scannlng electrochemical mlcroscopy (SECM) Is descrlbed. I n thls technlque the electrolysls current that flows as an ultramicroelectrode tlp (diameter ca. 10 gm) Immersed In a soiutlon Is moved above a substrate surface is used to characterize processes and structural features of the substrate. Modes of Operation consldered Include collectlon modes, where products electrogener...

To study the nature of electrochemical property III-nitrides, we examined here behaviour a n -GaN anodic oxidation reaction within voltage range 5–20 V in inorganic electrolytes as pH value varied from 0 to 13.

Silicon (Si) is a promising material for lithium ion battery (LIB) anodes due to its high specific capacity. To overcome its shortcomings such as insulation property and large volume change during the charge-discharge process, a novel hybrid system, Si nanoparticles encapsulated in hollow graphitized carbon nanofibers, is studied. First, electrospun polyacrylonitrile (PAN)-Si hybrid nanofibers ...
