Oxidized Nano-Porous-Silicon Buffer Layers for Suppressing the Visible Photoresponsivity of ZnO Ultraviolet Photodetectors on Si Substrates

<table>Photoresponse spectra of ZnO photodiodes prepared on Si substrates with NPS and ONPS buffer layers, respectively. For comparison purpose, the photoresponse spectra of a bare NPS layer on a Si substrate were also included in the figure.</table>
