Embodiment Construction

[0015]The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

[0016]Referring to FIG. 1, one embodiment of an SBD 10 is provided. The SBD 10 includes a first metal layer 12, a semiconductor layer 14, and a second metal layer 16. The first metal layer 12 and the second metal layer 16 are spaced from each other and electrically connected with the semiconductor layer 14. The first metal layer 12 is in Schottky contact with the semiconductor layer 14, and a Schottky barrier is formed at a first interface 141 between the first metal layer 12 and the semiconductor layer 14. The second metal layer 16 is in ohmic contact with the semiconductor layer 14, and a small barrier or even no contact barrier is formed at a ...

Abstract

A Schottky barrier diode includes a first metal layer, a second metal layer separated form the first metal layer, and a semiconductor layer. The semiconductor layer is in Schottky contact with the first metal layer and in ohmic contact with the second metal layer. The semiconductor layer includes an insulated polymer material and a number of carbon nanotubes dispersed in the insulated polymer material.

Description

RELATED APPLICATIONS[0001]This application claims all benefits accruing under 35 U.S.C. §119 from China Patent Application No. 201110215767.2, filed on Jul. 29, 2011 in the China Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to a Schottky barrier diode.[0004]2. Discussion of Related Art[0005]A Schottky barrier diode (SBD) has low power, high current and super high speed; therefore, it can be applied in various of electronic devices. The SBD generally includes a noble metal and a semiconductor layer contacted with the noble metal. A barrier having a rectifying property is formed in an interface between the noble metal and the semiconductor layer. The conventional semiconductor layer is made of rigid inorganic material, therefore, it is not suitable for flexible electronic devices.[0006]An organic material of copper phthalocyanine can be used in an SBD as a semiconductor ...
