<p><P>PROBLEM TO BE SOLVED: To provide a rectifier element such as a detection element in which a cutoff frequency can be increased in a view point different from the reduction in size of a structure. <P>SOLUTION: The rectifier element includes: a Schottky barrier portion 101 including a Schottky electrode 111; a barrier portion 102 having a rectifying property with respect to a majority carrier in the Schottky barrier portion 101; and an ohmic electrode 103 in electrical contact with the rectifying barrier portion 102, in which each of the Schottky barrier portion 101 and the rectifying barrier portion 102 has an asymmetrical band profile whose gradient on one side is larger than that on the other side. The Schottky barrier portion 101 and the rectifying barrier portion 102 are connected so that the steep gradient side of the band profile is located on the side of the Schottky electrode 111 respectively. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
