Patent number: 9136400Abstract: In this junction element 1, when a forward voltage is applied, a depletion layer is formed in a semiconductor layer 2, prohibiting electrons present in an electrode layer 4 to move into the semiconductor layer 2. For this reason, a majority of holes in a semiconductor layer 3 do not disappear by recombination with conduction electrons in the semiconductor layer 2, but reach the electrode layer 4 while diffusing into the semiconductor layer 2. Accordingly, the junction element 1 can serve as a good conductor for holes, while avoiding the influence of a resistance value, and allows a current to flow therethrough at a level equal to or more than that achieved by a semiconductor element formed of a Si or SiC semiconductor.Type: GrantFiled: February 27, 2009Date of Patent: September 15, 2015Assignees: NISSAN MOTOR CO., LTD., NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGYInventors: Satoshi Tanimoto, Norihiko Kiritani, Toshiharu Makino, Masahiko Ogura, Norio Tokuda, Hiromitsu Kato, Hideyo Okushi, Satoshi Yamasaki
