  • Patent number: 10825920
    Abstract: Energy-filtered cold electron devices use electron energy littering through discrete energy levels of quantum wells or quantum dots that are formed through band bending of tunneling barrier conduction band. These devices can obtain low effective electron temperatures of less than or equal to 45K at room temperature, steep electrical current turn-on/turn-off capabilities with a steepness of less than or equal to 10 mV/decade at room temperature, subthreshold swings of less than or equal to 10 mV/decade at room temperature, and/or supply voltages of less than or equal to 0.1 V.
    Type: Grant
    Filed: November 26, 2019
    Date of Patent: November 3, 2020
    Assignee: Board of Regents, The University of Texas System
    Inventors: Seong Jin Koh, Pradeep Bhadrachalam, Liang-Chieh Ma
