摘要:
Patterned single crystals and related devices are facilitated. According to an example embodiment of the present invention, organic semiconducting single-crystals are manufactured using a plurality of surface regions on a substrate. The diffusivity and/or the rate of desorption is controlled at each surface region and at the substrate to grow at least one organic semiconducting single crystal at each surface region from a vapor-phase organic material. This control is effected, for example, before and/or during the introduction of vapor-phase organic material to the surface regions. In some embodiments, the surface regions include an organic film such as octadecyltriethoxysilane (OTS), and in other embodiments, the surface regions include carbon nanotube bundles, either of which can be implemented to exhibit a surface roughness and/or other characteristics that facilitate selective crystal nucleation.

The present invention provides an organic field-effect transistor (OFET) and a method of fabricating the OFET. The OFET, configured to function as a p-type semiconductor, includes a substrate having a top surface and a semiconductor layer located over the top surface. The semiconductor layer comprises organic semiconductor molecules. Each of the organic semiconductor molecules includes a core having conjugated pi bonds, a fluorinated alkyl group, and an alkyl spacer group having a chain of two or more carbon atoms. One end of the chain is bonded to the fluorinated alkyl group and another end of the chain is bonded to the core. Substituents coupled to the carbon atoms have an electronegativity of less than about 4.

摘要:
A polarized organic photonics device, including an LED or photovoltaic device, is comprised of a first conductive layer or electrode coated with a friction transferred alignment material, a photoactive material, and a second electrically conductive layer or electrode. The alignment material provides for the orientation of the subsequently deposited photoactive material such that the photoactive material interacts with or emits light preferentially along a selected polarization axis. Additional layers and sublayers optimize and tune the optical and electronic responses of the device.
