摘要:
The present invention relates to an organic transistor comprising a conductive element which forms a drain; a conductive element which forms a source located away from the drain; a conductive element which forms a gate having a surface which faces the drain and a surface which faces the source; a semiconducting layer which is in contact with the drain and the source; and a dielectric layer located between, firstly, the gate and, secondly, the source and the drain with the dielectric layer having a dielectric permittivity which varies depending on its thickness,According to the invention, the dielectric layer comprises a layer of a first dielectric material having a dielectric permittivity of less than four in which there is formed, at least between said opposite-facing surfaces, a volume of a second material, said volume having an overall cross-section which tapers from gate towards the space between drain and source and in that the relative dielectric permittivity of the second material exceeds four.

The mixture according to the invention comprises: molecules having physicochemical properties, monomers, carrying crosslinkable functions, and representing at least 30% by weight of the mixture, advantageously at least 40% by weight. This mixture is used in particular in methods for fabricating and sealing crystal-containing cells or batteries, consisting of juxtaposed troughs.
摘要:
The invention relates to a method for manufacturing adjacent first and second areas of a surface, said areas consisting, respectively, of first and second materials that are different from each other. Said method involves: depositing a first liquid volume that encompasses the first area and comprises a solvent in which the first material is dispersed; depositing a second liquid volume that encompasses the second area and comprises a solvent in which the second material is dispersed; and removing the solvents. According to the invention, the solvents of the first and second volumes are immiscible, and the second volume is simultaneously or consecutively deposited with the deposition of the first volume, before the first volume reaches the second area.
