Nano antenna array for terahertz detection
(2011)Infrared (IR) detectors have been fabricated consisting of antenna-coupled metal-oxide-metal diodes (ACMOMDs). These detectors were defined using electron beam lithography with shadow evaporation metal deposition. They are ... -
Light extraction from surface plasmons and waveguide modes in an organic light-emitting layer by nanoimprinted gratings
(Optical Society of American (OSA), 2011)Organic light-emitting diodes (OLEDs) usually exhibit a low light outcoupling efficiency because a large fraction of power is lost to surface plasmons (SPs) and waveguide modes. In this paper it is demonstrated that periodic ... -
Nanostructured interfaces in polymer solar cells
(2010)The morphology in organic photovoltaics plays a key role in determining the device efficiency. We propose a method to fabricate bilayer devices with controlled nanostructured interfaces by combining nanoimprinting and ... -
Printed array of thin-dielectric metal-oxide-metal (MOM) tunneling diodes
(2011)A large area array of metal-oxide-metal (MOM) tunneling diodes with an ultrathin dielectric (∼3.6 nm aluminum oxide) have been fabricated via a transfer-printing process. The MOM diodes exhibit an excellent tunneling ... -
Spray coated indium-tin-oxide-free organic photodiodes with PEDOT:PSS anodes
(American Institute of Physics Inc., 2014)In this paper we report on Indium Tin Oxide (ITO)-free spray coated organic photodiodes with an active layer consisting of a poly(3-hexylthiophen) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) blend and ... -
A hybrid CMOS-imager with a solution-processable polymer as photoactive layer
(2012)The solution-processability of organic photodetectors allows a straightforward combination with other materials, including inorganic ones, without increasing cost and process complexity significantly compared with conventional ...
