Engineering of semiconductor compounds via electrochemical technologies for nano-microelectronic applications

Abstract

The paper is focused on electrochemical approaches for nanostructuring of semiconductor compounds with further applications in micro-nanoelectronic devices. A cost-effective technology for nanowires and nanotubes obtaining by pulsed electrochemical deposition is presented. Functionalization of elaborated nanostructures with gold or platinum via electroplating improve the properties of the nanostructures. A varicap devise based on Pt/porous GaP with a capacitance density variation of about 6x10-3 pF/V for 1 μm2 of surface is presented.
