A method fabricates ICs in which organic semiconductor crystallites serve as active channels of semiconductor devices. The method includes providing a substrate with a surface that has a preselected pattern of adhesion sites located thereon. The adhesion sites are prepared to adhere crystallites of an organic semiconductor. The method also includes applying a plurality of crystallites of the organic semiconductor to the surface to enable a portion of the applied crystallites to adhere at the prepared adhesion sites.

An electronic odor sensor includes first and second amplifiers, a biasing network, and a device connected to receive the output signals from the first and second amplifiers. The device is configured to correlate the received output signals to the presence or absence of an odor. The first and second amplifiers have respective first and second organic semiconductor layers and are configured to produce output signals responsive to the conductivities of their respective organic semiconductor layers. The conductivities of the organic semiconductor layers are responsive to voltages applied to associated ones of the amplifiers and to the presence of the odor. The biasing network applies the voltages to the amplifiers.

Hybrid semiconducting-dielectric materials and electronic or electro-optic devices using the hybrid semiconducting-dielectric materials. Hybrid semiconducting-dielectric materials comprise molecules that have a core section that provides an n-type semiconducting property and side chains that provide a dielectric property to a layer of hybrid semiconducting-dielectric material. Specific hybrid semiconducting-dielectric materials include tetracarboxylic diimide compounds having sidechains comprising fluorine substituted aliphatic or aromatic moieties linked to the tetracarboxylic diimide structure by an alkylene or heteroalkylene linking group.

An electronic or electro-optic device has a first electrode, a second electrode spaced apart from the first electrode, and a dielectric layer disposed between the first and second electrodes. The dielectric layer has electrically insulating planar layers with intercalated ions therebetween such that the electrically insulating planar layers provide a barrier to impede movement of the intercalated ions to the first and second electrodes under an applied voltage while permitting a polarization of the dielectric layer while in operation.

An electro-optical modulator includes an optical waveguide for carrying an optical carrier wave and a control waveguide for carrying a control wave. The optical waveguide includes a cladding layer and a core. The two waveguides are collinear and overlap in an interaction region so that the refractive index of the optical waveguide responds to electric fields generated by the control wave in the interaction region. The refractive index of the cladding layer at the control wave's wavelength is higher than the refractive index of the core at the optical carrier wave's wavelength.
摘要:
An improved process for forming devices utilizing patterned organic semiconductor films is provided. The process involves treating a surface to selectively provide regions of greater affinity and lesser affinity for an organic semiconductor or an organic semiconductor solution. When the organic semiconductor, or solution comprising the semiconductor, is deposited on the treated surface, either the organic semiconductor or the organic semiconductor solution dewets from the lesser affinity regions or the resultant film adheres only weakly to the lesser affinity regions such that selective removal is readily performed. And even where such removal is not performed, the portions of the organic semiconductor film overlying the greater affinity regions exhibit higher mobility and better film continuity relative to the other portions of the film.
