  • CANISTER WITH HEATER
    Publication number: 20110247592
    Abstract: Disclosed herein is a canister mounted in a vehicle to reduce the discharge of fuel gas. The canister of the present invention includes at least one pocket installed in a canister housing. The pocket divides the inner space of the canister housing into first and second spaces. A heater is inserted into the pocket from the outside of the canister housing. The heater generates heat during running of an engine to heat active carbon filled in the canister. When the active carbon is heated, fuel gas adsorbed onto the active carbon in a liquid phase is easily evaporated and supplied to the engine. The heater can significantly improve desorption efficiency of the fuel gas by the active carbon.

    Abstract: There are provided a method of manufacturing a zinc oxide semiconductor, and a zinc oxide semiconductor manufactured using the method. A metal catalyst layer is formed on a zinc oxide thin film that has an electrical characteristic of a n-type semiconductor, and a heat treatment is performed thereon so that the zinc oxide thin film is modified into a zinc oxide thin film having an electrical characteristic of a p-type semiconductor. Hydrogen atoms existing in the zinc oxide thin film are removed by a metal catalyst during the heat treatment. Accordingly, the hydrogen atoms existing in the zinc oxide thin film are removed by the metal catalyst and the heat treatment, and the concentration of holes serving as carriers is increased. That is, an n-type zinc oxide thin film is modified into a highly-concentrated p-type zinc oxide semiconductor.
