TL;DR: Bottom-gate, top-contact organic thin-film transistors with excellent static characteristics and fast unipolar ring oscillators with significant contribution of the transfer length to the relation between channel length, contact length, Contact resistance, effective mobility, and cutoff frequency are fabricated.

TL;DR: Low-voltage p-channel and n-channel organic transistors with channel lengths down to 0.5 μm using four small-molecule semiconductors and ultra-thin dielectrics based on two different phosphonic acid monolayers are fabricated on plastic substrates and studied in terms of effective mobility, intrinsic mobility and contact resistance.

TL;DR: In this article, bottom-gate, top-contact (inverted staggered) organic thin-film transistors with a channel length of 1μm have been fabricated on flexible plastic substrates using the vacuum-deposited small-molecule semiconductor 2,9-didecyl-dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (C10-DNTT).

TL;DR: A 3.3 V 6-bit binary-weighted current-steering digital-to-converter converter (DAC) using low-voltage organic p-type thin-film transistors (OTFTs) is presented, marking records in speed and compactness owing to an OTFT fabrication process that is based on high-resolution silicon stencil masks.

TL;DR: In this paper, high-performance, lowvoltage organic thin-film transistors based on dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) are thoroughly characterized with respect to their optical functionality.
