  • Publication number: 20200217816
    Abstract: Described herein are ultrasensitive gas sensors based on a vertical-channel organic semiconductor (OSC) diode, along with methods for making such devices, and uses thereof. The organic sensing layer comprises a fused thiophene-based organic polymer that connects top and bottom electrodes to deliver a vertical current flow. The nano-porous top-electrode structure enables the contact between ambient gas molecules and the vertical organic channel. The device has high sensitivity, is easy to process, and has a long shelf life.

  • Patent number: 9236492
    Abstract: An active device provided by the invention is disposed on a substrate and includes a gate, a gate insulating layer, an oxide semiconductor channel layer, a plurality of nano conductive wires, a source and a drain. The gate insulating layer is disposed between the gate and the oxide semiconductor channel layer. The nano conductive wires are distributed in the oxide semiconductor channel layer, in which the nano conductive wires do not contact the gate insulating layer and the nano conductive wires are arranged along a direction and not intersected with each other. The source and the drain are disposed on two sides opposite to each other of the oxide semiconductor channel layer, in which a portion of the oxide semiconductor channel layer is exposed between the source and the drain.
