ZnO Nanowires Vertically Oriented by Pulsed Laser Deposition on Glass Substrates

詳細技術說明

Lithography techniques such as electron-beam lithography and proximal probe patterning have been utilized for the fabrication of one-dimensional ZnO nanowires; however these processes are generally costly and slow. In addition, chemical synthesis of ZnO nanowires suffers from a lack of control in the functionality of the nanostructures. Researchers from King Abdullah University of Science and Technology have successfully fabricated very high quality ZnO nanowires through a pulsed laser deposition (PLD) technique. PLD has been recognized as an effective method to produce high-quality epitaxial oxide thin films at a low temperature and has been used to produce various nanostructures like nanorods, nanoparticles, and nanowalls. In the PLD process, desirable atoms and ions are deposited on a substrate to form a thin film.

*Abstract

Nanostructured zinc oxide materials have been intensively evaluated due to their unique electronic, optic, and photonic properties. One-dimensional zinc nanowires have novel electrical, mechanical, chemical and optical properties as a result of surface and quantum confinement effects with applicability in photovoltaics due to several performance and processing benefits, such as a direct path for charge transport and the large surface area offered by the nanostructure geometry. However, assembly of individual atoms into one-dimensional structures in a fast and controllable way is challenging.
