  • Optically addressed, thermionic electron beam device
    Patent number: 10741352
    Abstract: An electron beam source is provided that includes a vessel forming a chamber, a cathode disposed within the chamber, the cathode comprising a low dimensional electrically conductive material having an anisotropic restricted thermal conductivity, an electrode disposed in the chamber, the electrode being connectable to a power source for applying a positive voltage to the electrode relative to the cathode for accelerating free electrons away from the cathode to form an electron beam when the cathode is illuminated by electromagnetic (EM) radiation such that the cathode thermionically emits free electrons, and an electron emission window in the chamber for passing a generated electron beam out of the chamber. An electron microscope that incorporates the electron beam source is also provided.
    Type: Grant
    Filed: December 15, 2017
    Date of Patent: August 11, 2020
    Assignees: THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITY, THE UNIVERSITY OF BRITISH COLUMBIA
