For the practical optoelectronic applications based on the ZnO nanowires, control the growth position of ZnO nanowires is essentially required. In this paper, we describe progress of synthesis the patterned growth of ZnO nanowires by chemical vapor deposition method and nanoparticle assisted pulsed laser deposition method using nano-imprinting technique.
This paper describes the experimental results of our recent attempt to synthesize device quality ZnO thin films on silicon and sapphire substrates by means of chemical vapor deposition. The surface features and crystal quality of these films are studied by scanning electron microscope and optical spectroscopy, respectively. Although it was not successful to deposit crystalline thin film on silicon...
In this work, the effect of substrate position on the formation of ZnO nanostructures synthesized by thermal evaporation of zinc oxide (ZnO) and carbon nanotubes (CNTs) on silicon substrate is investigated. The multi-wall CNT powder made by chemical vapor deposition was mixed with ZnO powder with a molar ratio of 1:1. The source material was put into the middle of chamber while Si substrates were...
Thin film ZnO/Si heterojunction solar cells were explored for their potentially low cost application. Microcrystalline silicon (??c-Si) deposited by metal induced growth (MIG) demonstrated viable photo response as a thin film base layer. Modeling using AMPS-1D was performed on various heterostructures. In thin film devices, Interface defects of 8.8??1011 1/cm2-eV were shown to significantly reduce...
Zinc oxide (ZnO) nanowire networks have been proposed as an alternative to organic and amorphous semiconductors for plastic electronics. Although the mobility of the ZnO networks is lower than that of individual nanowires, they offer the advantages of high transparency and flexibility. A major drawback of using individual nanowires in nano or microelectronic applications is the lack of a manufacturable...
