Abstract:
1. A method for making a Schottky barrier diode, comprising: providing a first metal layer, a second metal layer and a carbon nanotube composite material, wherein the carbon nanotube composite material comprises an insulated polymer and a plurality of carbon nanotubes dispersed in the insulated polymer; and applying the carbon nanotube composite material on the first metal layer and the second metal layer to form a semiconductor layer, wherein the semiconductor layer is in Schottky contact with the first metal layer and in ohmic contact with the second metal layer, wherein the carbon nanotube composite material is a liquid carbon nanotube composite material, applying the carbon nanotube composite material on the first metal layer comprises sub-steps of: dropping the liquid carbon nanotube composite material on a surface of the first metal layer; and putting the first metal layer with the liquid carbon nanotube composite material thereon into a vacuum environment, wherein locating the second metal layer on a surface of the carbon nanotube composite material opposite to the first metal layer comprises sub-steps of: curing the liquid carbon nanotube composite on the first metal layer to be a quasi-solid carbon nanotube composite material; applying the second metal layer on the quasi-solid carbon nanotube composite material; and curing the quasi-solid carbon nanotube composite until the quasi-solid carbon nanotube composite is completely cured, thereby forming the semiconductor layer.
