  • Systems and methods for tailored microstructures using templated grain nucleation
    Patent number: 10822688
    Abstract: Methods for controlled microstructure creation utilize seeding of amorphous layers prior to annealing. Seed crystals are formed on an amorphous layer or layers. The material, size, and spacing of the seed crystals may be varied, and multiple seed layers and/or amorphous layers may be utilized. Thereafter, the resulting assembly is annealed to generate a crystalline microstructure. Via use of these methods, devices having desirable microstructural properties are enabled.
    Type: Grant
    Filed: July 25, 2019
    Date of Patent: November 3, 2020
    Assignee: Arizona Board of Regents on behalf of Arizona State University
    Inventors: Jagannathan Rajagopalan, Rohit Sarkar
