TL;DR: In this paper, a printed network of single-walled carbon nanotubes (SWNTs) is integrated with ultrathin layers of the organic semiconductor pentacene to produce bendable, transparent thin-film transistors on plastic substrates.
Abstract: Electrodes based on printed networks of single-walled carbon nanotubes (SWNTs) are integrated with ultrathin layers of the organic semiconductor pentacene to produce bendable, transparent thin-film transistors on plastic substrates The physical and structural properties of the SWNTs lead to the remarkably good electrical contacts with the pentacene Optical transmittances of ∼70%, device mobilities >05cm2V−1s−1, ON/OFF ratios >105 and tensile strains as large as 18% are achieved in devices of this type These characteristics indicate promise for applications in power conserving flexible display systems and other devices

TL;DR: Patterns composed of solvent wetting and dewetting regions promote lateral confinement of solution-sheared and lattice-strained TIPS-pentacene crystals, and this lateral confinement causes aligned crystal growth.
Abstract: Patterns composed of solvent wetting and dewetting regions promote lateral confinement of solution-sheared and lattice-strained TIPS-pentacene crystals. This lateral confinement causes aligned crystal growth, and the smallest patterns of 0.5 μm wide solvent wetting regions promotes formation of highly strained, aligned, and single-crystalline TIPS-pentacene regions with mobility as high as 2.7 cm(2) V(-1) s(-1) .

TL;DR: In this article, the decay of an excited singlet exciton into two triplet excitons is suggested to be an important fluorescence quenching channel in crystalline tetracene and its corresponding rate is estimated to be ∼ 4 × 10 10 to 10 12 sec −1.

TL;DR: In this paper, an organic field effect transistor with pentacene active material and a ferroelectric copolymer poly (vinylidene fluoride-trifluoroethylene) as the gate insulator was fabricated.
Abstract: Organic field-effect transistors were fabricated with pentacene as the active material and a ferroelectric copolymer poly(vinylidene fluoride–trifluoroethylene) as the gate insulator. As-prepared devices showed normal p-type transistor operation. The ON- and OFF-states could be written to the device by applying appropriate voltages to the gate with respect to short-circuited source and drain electrodes. The devices exhibited excellent memory retention properties.

TL;DR: In this article, the Y function method (YFM) was introduced to evaluate the low-field mobility without the access or contact resistance influence in pentacene OFETs, and the YFM proved to be a fast and precise alternative method for the contact resistance evaluation, although such contact resistance is a constant as compared to the widely accepted variable one with respect to the gate voltage.
Abstract: Organic field-effect transistors (OFETs) suffer from limitations such as low mobility of charge carriers and high access resistance. Direct and accurate evaluation of these quantities becomes crucial for understanding the OFETs properties. We introduce the Y function method (YFM) to pentacene OFETs. This method allows us to evaluate the low-field mobility without the access or contact resistance influence. The low-field mobility is shown to be more appropriate than the currently applied field-effect mobility for the OFETs’ performance evaluation. Its unique advantage is to directly suppress the contact resistance influence in individual transistors, although such contact resistance is a constant as compared to the widely accepted variable one with respect to the gate voltage. After a comparison in detail with the transmission-line method, the YFM proved to be a fast and precise alternative method for the contact resistance evaluation. At the same time, how the contact resistance affects the effective mobi...
