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 nano - microelectronic 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 improves the properties of the nanostructures. An optimization of the varicap design to increase the capacitance is proposed and discussed as well as the optimization of pulsed electrochemical deposition of several hundred micrometer long Pt nanotubes is performed. Herein, the elaboration of contacts to GaAs nanowires via different approaches for photoelectrical investigations is reported.
