  • Chemical bath deposition of SnO2 and Cd2SnO4 thin films 
    KHALLAF, Hani; CHEN, Chia-Ta; CHANG, Liann-Be; LUPAN, Oleg; DUTTA, Aniruddha; HEINRICH, Helge; HAQUE, Firoze; DEL BARCO, Enrique; CHOW, Lee (ELSEVIER, 2012)
    A new approach of chemical bath deposition (CBD) of SnO2 thin films is reported. Films with a 0.2μm thickness are obtained using the multi-dip deposition approach with a deposition time as little as 8–10min for each dip. ...
  • Comparison of Thermal Annealing versus Hydrothermal Treatment Effects on the Detection Performances of ZnO Nanowires 
    LUPAN, Oleg; MAGARIU, Nicolae; KHALEDIALIDUSTI, Rasoul; MISHRA, Abhishek Kumar; HANSEN, Sandra; KRÜGER, Helge; POSTICA, Vasile; HEINRICH, Helge; VIANA, Bruno; ONO, Luis Katsuya; CUENYA, Beatriz Roldan; CHOW, Lee; ADELUNG, Rainer; PAUPORTÉ, Thierry (American Chemical Society, 2021)
    A comparative investigation of the post-electroplating treatment influence on the gas detecting performances of single ZnO nanorod/nanowire (NR/NW), as grown by electrochemical deposition (ECD) and integrated into nanosensor ...
  • Crossed zinc oxide nanorods for ultraviolet radiation detection 
    CHAI, Guangyu; LUPAN, Oleg; CHOW, Lee; HEINRICH, Helge (ELSEVIER, 2009)
    An ultraviolet photosensor has been successfully constructed by the in situ lift-out method in a focused ion beam system. The prototype consists of individual naturally self-assembled crossed ZnO nanorods grown by an aqueous ...
  • Focused-ion-beam fabrication of ZnO nanorod-based UV photodetector using the in-situ lift-out technique 
    LUPAN, Oleg; CHOW, Lee; CHAI, Guangyu; CHERNYAK, Leonid; LOPATIUK-TIRPAK, Olena; HEINRICH, Helge (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2008)
    Abstract ZnO nanorods and nanowires are promising candidates as new types of high-sensitivity ultraviolet (UV) photodetectors due to their wide bandgap and large aspect ratio. In this study, single-crystalline ZnO nanorods ...
  • In-situ boron doping of chemical-bath deposited CdS thin films 
    KHALLAF, Hani; CHAI, Guangyu; LUPAN, Oleg; CHOW, Lee; HEINRICH, Helge; PARK, S.; SCHULTE, Alfons (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2009)
    In-situ boron doping of CdS using chemical-bath deposition (CBD) is reported. The effect of B doping on optical properties, as well as electrical properties, crystal structure, chemistry, and morphology of CdS films is ...
  • Investigation of chemical bath deposition of CdO thin films using three different complexing agents 
    KHALLAF, Hani; CHEN, Chia-Ta; CHANG, Liann-Be; LUPAN, Oleg; DUTTA, Aniruddha; HEINRICH, Helge; SHENOUDA, A.; CHOW, Lee (ELSEVIER, 2011)
    Chemical bath deposition of CdO thin films using three different complexing agents, namely ammonia, ethanolamine, and methylamine is investigated. CdSO4 is used as Cd precursor, while H2O2 is used as an oxidation agent. ...
  • Nanofabrication and characterization of ZnO nanorod arrays and branched microrods by aqueous solution route and rapid thermal processing 
    LUPAN, Oleg; CHOW, Lee; CHAI, Guangyu; ROLDAN, Beatriz; NAITABDI, Ahmed; SCHULTE, Alfons; HEINRICH, Helge (ELSEVIER, 2007)
    This paper presents an inexpensive and fast fabrication method for one-dimensional (1D) ZnO nanorod arrays and branched two-dimensional (2D), three-dimensional (3D) – nanoarchitectures. Our synthesis technique includes the ...
