Surface texturing by solution deposition for omnidirectional antireflection
(Original publisher: Applied Physics LettersUniversity of Texas at Arlington, 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 ...
Solution-processed omnidirectional antireflection coatings on amorphous silicon solar cells
(Original publisher: Journal of Applied PhysicsUniversity of Texas at Arlington, 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 ...
Microstructured surface design for omnidirectional antireflection coatings on solar cells
(Original publisher: American Institute of Physics, 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 ...
Colloidal quantum dot absorption enhancement in flexible Fano filters
(IEEE, 2010-02-25)
We report here modified absorption property of colloidal quantum dots CQDs inside flexible Fano
filters—made of patterned single crystalline silicon nanomembrane transferred onto flexible plastic
substrates. Enhanced ...
Encapsulation for efficient electrical injection of photonic crystal defect mode surface-emitting lasers
(IEEE, 2006-01-31)
We propose and report an encapsulated photonic crystal concept for efficient electrical injection of
photonic crystal surface-emitting lasers. Detailed rate equation analysis reveals a significant
threshold current ...
Resonance control of membrane reflectors with effective index engineering
(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 ...
Fano filters based on transferred silicon nanomembranes on plastic substrates
(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
(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 ...
Coupled Bilayer Photonic Crystal Slab Electro-Optic Spatial Light Modulators
(IEEE, March 1, 2)
We demonstrate here a surface-normal ultracompact Fano resonance electro-optic spatial light modulator employing a stacked photonic crystal membrane capacitor-like structure. Vertically coupled optical resonance near 1.5 ...
Optical Refractive Index Sensing Based on High-Q Bound States in the Continuum in Free-Space Coupled Photonic Crystal Slabs
(MDPI, 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 ...
