TLDR
In this paper, the performance of organic field effect transistors (OFETs) is examined in terms of field effect mobility and on-off current ratio, and the most prominent fabrication techniques are described.Abstract:
Organic field-effect transistors (OFETs) were first described in 1987. Their characteristics have undergone spectacular improvements during the last two or three years. At the same time, several models have been developed to rationalize their operating mode. In this review, we examine the performance of OFETs as revealed by recently published data, mainly in terms of field-effect mobility and on–off current ratio. We compare the various compounds that have been used as the active component, and describe the most prominent fabrication techniques. Finally, we analyze the charge transport mechanisms in organic solids, and the resulting models of OFETs.read more

Theoretical study of long oligothiophene dications: bipolaron vs polaron pair vs triplet state.
Sanjio S. Zade,Michael Bendikov +1 more
TL;DR: Results from isodesmic reactions show that the stability of oligothiophene cation radicals over dications is inversely proportional to chain length, and the relative stability of the bipolaron versus the polaron pair were supported by CASSCF calculations.

Photoinduced transient stark spectroscopy in organic semiconductors: a method for charge mobility determination in the picosecond regime
Juan Cabanillas-Gonzalez,Tersilla Virgili,Alessio Gambetta,Guglielmo Lanzani,Thomas D. Anthopoulos,Dago M. de Leeuw +5 more
TL;DR: Subpicosecond photoinduced Stark spectroscopy experiments are carried out for measuring charge carrier mobility in organic semiconductors and two distinct transport regimes are revealed: a short-lived state of high mobility and a transient towards the trap limited transport, associated with the mesoscopic structure of the medium.
