Abstract
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 optical absorption was obtained both experimentally and theoretically, when the CQD absorption peak spectrally overlaps with Fano resonance peak. On the other hand, suppressed absorption was observed when the Fano resonance has no spectral overlap with the CQD absorption bands. © 2010 American Institute of Physics.

Adrienne Stiff-Roberts
Dr. Stiff-Roberts received both the B.S. degree in physics from Spelman College and the B.E.E. degree in electrical engineering from the Georgia Institute of Technology in 1999. She received an M.S.E. in electrical engineering and a Ph.D. in applied physics in 2001 and 2004, respectively, from the University of Michigan, Ann Arbor, where she investigated high-temperature quantum dot infrared photodetectors grown by molecular beam epitaxy. Dr. Stiff-Roberts joined Duke University in August 2004, and she is a Professor of Electrical and Computer Engineering.
Dr. Stiff-Roberts' research interests include the synthesis of multi-component and hybrid (organic-inorganic) materials using a novel approach for organic-based thin film deposition that combines solution and vacuum-processing. Known as emulsion-based, resonant infrared matrix-assisted pulsed laser evaporation (RIR-MAPLE), this technique offers a completely new way to integrate novel functions into organic-based films and devices that are difficult, if not impossible, to achieve otherwise. Research efforts include materials synthesis and characterization to investigate the fundamental mechanisms of thin-film growth using RIR-MAPLE, as well as device fabrication and characterization for a broad range of applications (especially optoelectronic and energy devices).
