Publication number: 20150292113Abstract: The present invention relates to a metal single crystal in which a metal element is substituted, wherein a metal element A is doped with a metal element B different from the metal element A to form A1-XBX, and a mixed single crystal is formed therefrom by high temperature melting (wherein the metal element A is any one of silver, copper, platinum and gold; the metal element B is any one of silver, copper, platinum and gold; and 0.01?x?0.09). Therefore, a metal single crystal, which is a mixed crystal with more superior electrical properties than a conventional metal, is formed by doping a metal with excellent electrical properties with a metal element different from the metal, and growing the doped metal into a mixed crystal.Type: ApplicationFiled: September 17, 2013Publication date: October 15, 2015Inventors: Se-young Jeong, Ji-young Kim, Yong-chan Cho, Sang-eon Park, Chae-ryong Cho
