Dual-gate organic phototransistor with high-gain and linear photoresponse

The conversion of light into electrical signal in a photodetector is a crucial process for a wide range of technological applications. Here we report a new device concept of dual-gate phototransistor that combines the operation of photodiodes and phototransistors to simultaneously enable high-gain and linear photoresponse without requiring...

Photocurrent Amplification in Bulk Heterojunction Organic Phototransistors with Different Donor–Acceptor Ratio

In this paper, the amplification of the photocurrent in organic phototransistors (OPTs) employing bulk heterojunctions (BHJs) with different donor–acceptor ratios has been studied. As a model system, poly[2-methoxy-5-(3’,7’-dimethyloctyloxy)-p-phenylene vinylene] (OC1C10-PPV) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) are used as...

Printable elastic conductors by in situ formation of silver nanoparticles from silver flakes

Printable elastic conductors promise large-area stretchable sensor/actuator networks for healthcare, wearables and robotics. Elastomers with metal nanoparticles are one of the best approaches to achieve high performance, but large-area utilization is limited by difficulties in their processability. Here we report a printable elastic conductor...
