    • 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 ...

    • Microstructured surface design for omnidirectional antireflection coatings on solar cells 

      Zhou, Weidong; Chen, Li; Yang, Hongjun; Tao, Meng (Original publisher: American Institute of PhysicsDepartment of Electrical Engineering, 2007-11-27)
      We recently demonstrated a new process for the formation of partially spherical structures as an omnidirectional antireflection coating (omni-AR). In this paper, we report the simulation results of the angular and spectral ...

    • Optical Refractive Index Sensing Based on High-Q Bound States in the Continuum in Free-Space Coupled Photonic Crystal Slabs 

      Liu, Yonghao; Zhou, Weidong; Sun, Yuze (MDPIDepartment of Electrical Engineering, The University of Texas at Arlington, 2017-08-11)
      High sensitivity (S) and high quality factor (Q) are desirable to achieve low detection limit in label-free optical sensors. In this paper, we theoretically demonstrate that single-layer and coupled bi-layer photonic crystal ...

    • 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 ...

    • Solution-processed omnidirectional antireflection coatings on amorphous silicon solar cells 

      Zhou, Weidong; Wang, Yuehui; Tummala, Rajesh; Chen, L.; Guo, L. Qing; Tao, Meng (Original publisher: Journal of Applied PhysicsUniversity of Texas at ArlingtonDepartment of Electrical Engineering, NanoFAB Center, 2009-05)
      Solution-processed spherical surface textures are demonstrated on commercial amorphous silicon solar cells. The texture is formed with a monolayer of silica microspheres by convective coating, followed by a spin-on-glass ...

    • Surface texturing by solution deposition for omnidirectional antireflection 

      Zhou, Weidong; Tao, Meng; Yang, Hongjun; Chen, Li (Original publisher: Applied Physics LettersUniversity of Texas at ArlingtonDepartment of Electrical Engineering, 2007-08)
      Surface texturing by solution deposition has been developed for antireflection in solar cells. The surface texture is formed by a monolayer of microscale silica particles partially immersed into a spin-on-glass film with ...
