Abstract: An organic thin film includes an organic crystalline phase, where the organic crystalline phase defines a surface having a surface roughness (Ra) of less than approximately 10 micrometers over an area of at least approximately 1 cm2. The organic thin film may be manufactured from an organic precursor and a non-volatile medium material that is configured to mediate the surface roughness of the organic crystalline phase during crystal nucleation and growth. The thin film may be formed using a suitably shaped mold, for example, and the non-volatile medium material may be disposed between a layer of the organic precursor and the mold during processing.

Abstract: An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.

Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling structure located at the input end for coupling light into the waveguide body, and an output coupling structure located at the output end for coupling light out of the waveguide body, where the waveguide body includes a layer of an organic solid crystal. Such an optical element may have low weight and exhibit good color uniformity.

Abstract: An organic field effect transistor includes a channel structure having a photoalignment layer and an organic semiconductor layer disposed directly over the photoalignment layer, where a charge carrier mobility varies along a thickness direction of the channel structure. The channel structure may define an active area between a source and a drain of the transistor and may include alternating layers of at least two photoalignment layers and at least two organic semiconductor layers. Each photoalignment layer is configured to influence an orientation of molecules within an overlying organic semiconductor layer and hence impact the mobility of charge carriers within the device active area while also advantageously decreasing the OFF current of the device.
