Flexible, Low‐Voltage and High‐Performance Polymer Thin‐Film Transistors and Their Application in Photo/Thermal Detectors

Electron Mobility Exceeding 10 cm2 V−1 s−1 and Band‐Like Charge Transport in Solution‐Processed n‐Channel Organic Thin‐Film Transistors

“…[18] In this process, a solution of Al(NO 3 ) 3 ·9H 2 O in ethanol (0.1 mol L −1 ) was spin-coated onto the SiO 2 , and the resulting film was baked Recent years have witnessed remarkable improvement of field effect mobility in organic thin film transistors (OTFTs). A few p-channel OTFTs of small-molecule [1] and polymer semiconductors [2][3][4] were reported to exhibit hole mobility over 10 cm 2 V −1 s −1 and even reaching 50 cm 2 V −1 s −1…”

Photosensitive and Flexible Organic Field‐Effect Transistors Based on Interface Trapping Effect and Their Application in 2D Imaging Array

“…OPTs are an attractive category of OFETs, which can be used as photodetectors, light‐induced switches, light‐triggered amplifiers, and image sensors, amongst other applications 15, 16, 17, 18, 19, 20, 21, 22, 23. In most studies on OPTs, it was the organic semiconductor itself, which exhibited photosensitivity.…”

Engineering of Amorphous Polymeric Insulators for Organic Field‐Effect Transistors

“…[75c] Recently, our group has fabricated a flexible, low-operating-voltage (≤−3 V) and high-mobility thin-film transistor by using n-octadecyltrichlorosilane(OTS)-modified poly(vinyl alcohol) (PVA). [54] As a high-ε r dielectric layer, PVA film can be prepared by a solution-processing method. After modified by OTS, the root-mean squared (RMS) roughness of PVA films can be reduced to 0.384 nm and the surface energy was decreased, which might lead to the formation of smaller π−π stacking distance and better TFT charge transport.…”
