Abstract:Highly transparent Ga doped ZnO thin films were prepared on (0001) sapphire substrates by pulsed laser deposition. Hall-effect measurement reveals that electron concentration of the ZnO films can be controlled between 10 18 and 10 21 cm -3 by adjusting Ga contents in the targets. Optical measurements show the transmittance is above 60 % in the near-infrared wavelength region for all Ga doped ZnO films. Meanwhile, these films also have high crystal quality and smooth surface when the electron concentration up t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
