  • Spin-polarized light-emitting diodes based on organic bipolar spin valves
    Patent number: 9799842
    Abstract: Spin-polarized organic light-emitting diodes are provided. Such spin-polarized organic light-emitting diodes incorporate ferromagnetic electrodes and show considerable spin-valve magneto-electroluminescence and magneto-conductivity responses, with voltage and temperature dependencies that originate from the bipolar spin-polarized space charge limited current.
    Type: Grant
    Filed: July 3, 2013
    Date of Patent: October 24, 2017
    Assignee: University of Utah Research Foundation
    Inventors: Zeev Valentine Vardeny, Tho Duc Nguyen, Eitan Avraham Ehrenfreund
