    • Fano filters based on transferred silicon nanomembranes on plastic substrates 

      Zhou, Weidong; Ma, Zhenqiang; Qiang, Zexuan; Yang, Hongjun; Chen, Li; Pang, Huiqing (IEEE, 2008-08-13)
      We report here the characteristics of surface-normal optical filters based on Fano resonances on patterned single crystalline silicon nanomembranes SiNMs , which were fabricated and transferred onto transparent plastic ...

    • Large-area InP-based crystalline nanomembrane flexible photodetectors 

      Zhou, Weidong; Yang, Weiquan; Yang, Hongjun; Qin, Guoxuan; Ma, Zhenqiang; Berggren, Jesper; Hammar, Mattias; Soref, Richard (IEEE, 2010-03-25)
      Large-area (3x3 mm2) flexible photodetectors were realized, based on crystalline InP semiconductor nanomembranes transferred to flexible polyethylene terephthalate substrates. Very low dark current a few microamperes ...

    • Resonance control of membrane reflectors with effective index engineering 

      Zhou, Weidong; Chuwongin, Santhad; Qiang, Zexuan; Chen, Li; Pang, Huiqing; Ma, Zhenqiang; Yang, Hongjun (IEEE, 2009-07-14)
      We report here broadband membrane reflectors based on Fano resonances in patterned silicon nanomembranes. Resonance control of the reflectors was realized either by partially removing buried oxide layer underneath the ...
