Abstract

Direct production of hydrogen fuel from water is of fundamental importance to alleviate the crisis that fossil resources confront nowadays. In this talk, I will discuss our recent development of 3D nanowire (NW) architectures for efficient photoelectrochemical (PEC) water splitting and the application of piezoelectric potential in water splitting reactions.  Firstly, we developed a surface-reaction-limited pulsed chemical vapor deposition (SPCVD) technique that decouples...

Abstract

In addition to conventional thin film structures, one-dimensional nanostructures such as semiconductor nanowires have attracted considerable attention due to their unique electronic, magnetic, optical, thermal and mechanical properties, complemented with superior structural quality and high surface-to-volume ratio. These nanowire properties offer great opportunity for their on-chip integration for optoelectronic, sensor, communication, and energy storage applications. Na...
