Organic field-effect transistors (OFETs) are the technology of choice for flexible electronic devices such as active-matrix (AM) displays. However, despite the continuous improvement of charge carrier mobility in organic semiconductors, the performan

We report on the superior transistor performance of the vertical organic field-effect transistor (V-OFET), achieving up to 30x higher on-currents than for reference horizontal organic thin film transistors (OTFTs) with 30 µm channel length and same

Graphene is a highly promising material for high speed, broadband, and multicolor photodetection. Because of its lack of bandgap, individually gated P- and N-regions are needed to fabricate photodetectors. Here we report a technique for making a larg

White organic LEDs are seen as one of the next generation light-sources, with their potential to reach internal efficiencies of unity and their unique appearance as large-area and ultrathin devices. However, to replace existing lighting technologies,

The authors present an alternative method for the determination of the charge carrier mobility of organic thin films. In contrast to known methods like space charge limited current, field effect transistor and time of flight approaches, we determine
