  • Heterojunction material and method of preparing the same
    Patent number: 11735417
    Abstract: A method of preparing a heterojunction material, includes forming a first transition metal on a substrate, forming a second transition metal on the first transition metal, and performing a plasma process containing a chalcogen source on the substrate. The first transition metal and the second transition metal are different from each other.
