  • Process for group III-V semiconductor nanostructure synthesis and compositions made using same
    Patent number: 10266409
    Abstract: Methods for producing nanostructures, particularly Group III-V semiconductor nanostructures, are provided. The methods include use of novel Group III and/or Group V precursors, novel surfactants, oxide acceptors, high temperature, and/or stable co-products. Related compositions are also described. Methods and compositions for producing Group III inorganic compounds that can be used as precursors for nanostructure synthesis are provided. Methods for increasing the yield of nanostructures from a synthesis reaction by removal of a vaporous by-product are also described.
    Type: Grant
    Filed: October 25, 2017
    Date of Patent: April 23, 2019
    Assignee: Nanosys, Inc.
    Inventors: Erik C. Scher, Mihai A. Buretea, William P. Freeman, Joel Gamoras, Baixin Qian, Jeffrey A. Whiteford
