Patents by Inventor Daniel Paget

Daniel Paget 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).

  • Local injector of spin-polarized electrons with semiconductor tip under light excitation
    Patent number: 7841016
    Abstract: The invention is directed to a spin-polarized electron injector using a semiconductor tip, in which tip the injected electrons are photocreated by a circularly polarized light excitation incident on the rear of the tip. This tip is supported by a transparent lever or cantilever and undergoes a surface treatment for the purpose of removing the surface oxide layer, to prevent said layer from reforming and to improve the proportion of injected electrons.
    Type: Grant
    Filed: May 23, 2006
    Date of Patent: November 23, 2010
    Assignee: Ecole Polytechnique
    Inventors: Daniel Paget, Jacques Peretti, Alistair Rowe, Georges Lampel, Bruno Gerard, Shailendra Bansropun
