The present invention relates to organic electroluminescent devices comprising a light-emitting layer B comprising two host materials, a n-type (electron-transporting) and a p-type (hole-transporting) host material, a thermally activated delayed fluorescence (TADF) material and an emitter material, which exhibits a narrow—expressed by a small full width at half maximum (FWHM)—deep-blue emission at an emission maximum of 440 to 475 nm.

Devices, circuits, and methods for fabricating circuits. A device having ambipolar characteristics includes a semiconductor layer and multiple gates, a source contact, and a drain contact coupled to the semiconductor layer. One channel may have elections as the majority charge carrier and may be formed proximate to one of the gates. Another channel may have holes as the majority charge carrier and be formed proximate another gate. Each of the channels is generally parallel to the other and couples the source contact to the drain contact. The device may be optimized by adjusting the work-functions in one or more of source and drain contacts or gates to compensate for differences in the effective masses of the majority carriers in each of the channels. The ambipolar nature of the devices allows logic circuits to be fabricated using one or two of the devices.

A method for enhancing charge carrier mobility of a field-effect transistor device. The method comprises generating uniaxial nanogrooves on a substrate and blade coating a solution comprising a semiconducting polymer onto the substrate. The polymer solution is spread onto the substrate in a direction parallel to the nanogrooves and a main-chain axis of the polymer is parallel to the nanogrooves. The semiconducting polymer can be then annealed, so that a polymer film is formed which is layered on top of the substrate, with polymer chains aligned parallel to a direction of charge carrier movement.
