Densily distributed ZnO nanorods have been grown by pulsed laser deposition by controlling the oxygen content during the nucleation and growth process. The XRD result suggests that ZnO nanorods are growing along the c axis and they are perpendicular to the surface of the substrate. Raman spectra of the as deposited ZnO nanorods support the XRD findings that the nanorod is of hexagonal wurtzite structure. AFM studies show that ZnO nanorods are densly distributed over the fused silica substrate. The transmittance of the nanorods are very high and the room-temperature photoluminescence measurements of these ZnO nanorods shown UV and visible emission. Electrical resistivity is very less compared to that of the bulk ZnO. The unique properties of ZnO nanorods may have a great potential in the application to the field-emission devices and nano-optics..

In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
