Abstract:
1. A method, comprising the acts of: a. depositing a dielectric layer on a substrate; b. locally charging a region of the dielectric layer, thereby forming a charged dielectric layer comprising at least two lateral regions having different charge levels; c. depositing a semiconductor material on the surface of the charged dielectric layer, thereby forming a semiconductor layer, such that all or a part of the semiconductor layer is in contact with all or a part of the charged dielectric layer, wherein the semiconductor material is selected from the group consisting of: organic semiconductors, polymeric semiconductors, nanostructured semiconductors, dry transferred semiconductors, and semiconductors that are mixtures of at least two of organic semiconductors, polymeric semiconductors, or nanostructured semiconductors; and the semiconductor layer comprises a first semiconductor region having a first threshold voltage, and a second semiconductor region having a second threshold voltage; and d. depositing at least one electrode over at least one of the regions in the dielectric layer.
