TLDR
This work demonstrates an organic channel light-emitting transistor operating at low voltage, with low power dissipation, and high aperture ratio, in the three primary colors, comparable to that of polycrystalline-silicon backplane transistor-driven display pixels.Abstract:
Intrinsic nonuniformity in the polycrystalline-silicon backplane transistors of active matrix organic light-emitting diode displays severely limits display size. Organic semiconductors might provide an alternative, but their mobility remains too low to be useful in the conventional thin-film transistor design. Here we demonstrate an organic channel light-emitting transistor operating at low voltage, with low power dissipation, and high aperture ratio, in the three primary colors. The high level of performance is enabled by a single-wall carbon nanotube network source electrode that permits integration of the drive transistor and the light emitter into an efficient single stacked device. The performance demonstrated is comparable to that of polycrystalline-silicon backplane transistor-driven display pixels.read more

TL;DR: It is demonstrated that the use of an appropriate hydroxyl-free gate dielectric—such as a divinyltetramethylsiloxane-bis(benzocyclobutene) derivative (BCB; ref. 6)—can yield n-channel FET conduction in most conjugated polymers, revealing that electrons are considerably more mobile in these materials than previously thought.

The physics of amorphous-silicon thin-film transistors
TL;DR: In this paper, the basic physics underlying the operation and key performance issues of amorphous-silicon thin-film transistors are discussed, and the transistors also show longer time threshold voltage shifts due to two distinct mechanisms: charge trapping in the silicon nitride gate insulator and metastable dangling bond state creation.
