Synthesis of silicon nanowire and carbon quantum dot hybrid nanostructure and study of its photoresponse property

Abstract

One and zero dimensional nanostructures and related hybrids have been widely studied for their possible application in electronic devices like in display devices, sensors and solar cells. Here in this article, chemical synthesis of n type Silicon nanowire and water soluble Carbon quantum dots (CQDs) have been reported. Hybrid nanostructure of Carbon quantum dots on top of n type Silicon nanowires (n-SiNW) were formed by spin coating the water soluble CQDs on top of n-SiNW. The hybrid nanostructure samples were studied and characterized by FESEM and HRTEM. The photocurrent property of the as prepared hybrid samples were studied in details for possible application in photovoltaic and optoelectronic devices.
