Boosting the efficiency of organic solar cells via plasmonic gold nanoparticles and thiol functionalized conjugated polymer
(Elsevier, 2022-11)Conjugated polymers are promising low-cost, lightweight, and flexible candidates for scalable photovoltaic applications to establish decarbonized energy technologies. However, they possess deficiencies in terms of their ... -
Enhanced confined microwave transmission by single subwavelength apertures
(Bilkent University, 2005)Grating-coupling phenomena between surface plasmons and electromagnetic waves are studied in the microwave spectrum using metallic circular apertures surrounded by an array of grooves. The measurements are performed in ... -
Hybridization of fano and vibrational resonances in surface-enhanced infrared absorption spectroscopy of streptavidin monolayers on metamaterial substrates
(2014)We present spectral hybridization of organic and inorganic resonant materials and related bio-sensing mechanism. We utilized a bound protein (streptavidin) and a Fano-resonant metasurface to illustrate the concept. The ... -
InGaN green light emitting diodes with deposited nanoparticles
(Elsevier BV, 2007)We grew an InGaN/GaN-based light-emitting diode (LED) wafer by metal-organic chemical vapor deposition (MOCVD), fabricated devices by optical lithography, and successfully deposited ellipsoidal Ag nano-particles by way of ... -
Plasmonic structures with extraordinary transmission and highly directional beaming properties
(Wiley Periodicals, 2006)We studied the grating-coupling phenomena between surface plasmons and electromagnetic waves in the microwave spectrum. We first present the experimental and theoretical results of an enhanced microwave transmission though ... -
Plasmonically enhanced hot electorn based optoelectronic devices
(Bilkent University, 2015-06)Hot electron based optoelectronic devices have been regarded as cost-e ective candidates to their conventional counterparts. The efficiency of conventional optoelectronic devices that rely on semiconductor photo-absorbers ... -
Resonant excitation of surface plasmons in one-dimensional metallic grating structures at microwave frequencies
(Institute of Physics Publishing, 2005)Grating-coupling phenomena between surface plasmons and electromagnetic waves were studied in the microwave spectrum using metallic gratings. Transmission measurements were carried out to observe the transmitted radiation ... -
Tuning plasmon induced reflectance with hybrid metasurfaces
(MDPI AG, 2019-03)Electrically tunable metasurfaces with graphene offer design flexibility to efficiently manipulate and control light. These metasurfaces can be used to generate plasmon-induced reflectance (PIR), which can be tuned by ...
