Polymer light‐emitting diodes with doped hole‐transport layers [PDF]

physica status solidi (a), 2011
AbstractWe demonstrate a solution processed bi‐layer PLED based on poly(p‐phenylene vinylene) derivatives using orthogonal solvents. To lower the voltage drop the hole transport layer (HTL) based on poly[2,5‐bis(2′‐ethylhexyloxy)‐co‐2,5‐bis(butoxy)‐1,4‐phenylenevinylene] (BEH/BB‐PPV (1:3)) is doped with tetracyano‐tetrafluoro‐quinodimethane (F4TCNQ ...

Photovoltaic devices with a PEDOT:PSS:WOx hole transport layer

RSC Advances, 2014
In this paper, we report a significantly improved fill factor (FF) of inverted poly(3-hexylthiophene) (P3HT) and indene-C60 bisadduct (ICBA) organic photovoltaic devices via surface modification. The influence of the poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate) (PEDOT:PSS) hole extraction layer (HEL) modified with tungsten oxide (WOx) on ...

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

Advanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control
