Patents by Inventor Tho Duc Nguyen

Tho Duc Nguyen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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
  • Device Comprising Deuterated Organic Interlayer
    Publication number: 20150194473
    Abstract: The present invention relates to devices that can be manipulated or controlled with a magnetic field, such as a spin-valve device, an organic light-emitting device, a compass, or a magnetometer. The devices of the invention comprise an organic interlayer comprising a deuterated organic material.
    Type: Application
