  1. 1. Photochemical and Photoelectric Applications of II-VI Semiconductor Nanomaterials

    Författare :Abhilash Sugunan; Mamoun Muhammed; Lars Kloo; KTH; []
    Nyckelord :ZnO; Nanowire arrays; Photocatalysis; Nanofibers; CdTe; Nanotetrapods; Ostwalds ripening; Photoconduction; Nano-gap electrodes;

    Sammanfattning : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated two different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdTe nanotetrapods synthesized by solution-based thermal decomposition of organo-metallic precursors.
