Photonic Crystal Diode Resonator for Modulated Field Emission from Cold Cathode

摘要

PURPOSE: A photonic crystal diode resonator for modulated field emission from a cold cathode is provided to overcome transit time effect by overcoming a line defect through a waveguide path of an external electromagnetic wave. CONSTITUTION: A photonic crystal diode resonator(200) includes a first metallic substrate(210), a second metallic substrate(220) and plural dielectric bars(230). A 2D photonic crystal structure of the plural dielectric bars includes a point defect and a line defect. A cold cathode(211) is placed on the point defect of the first metallic substrate.
