▎ 摘　　要

NOVELTY - The full two-dimensional vacuum tube includes two-dimensional insulating material as precursor material of vacuum channel in the vacuum tube. A two-dimensional conductive material transistor is utilized as thermal field emission source-cathode, and the metal conductive material is utilized as electron collection electrode-anode. USE - Full two-dimensional vacuum tube used in high-precision vacuum pressure sensors, nanoelectromechanical system (NEMS) micro-motor system, radiation-resistant thermal field emission power transistor, electronic circuit, glow display, X-ray generator, microwave oscillator and microelectronic and high power electronic circuit. ADVANTAGE - Since the full two-dimensional vacuum tube is prepared in array, the integration into modular circuit is enabled. The stability of the anode voltage is ensured, stable thermal field emission current is provided, the size is reduced, and quality of the device is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of full two-dimensional vacuum tube. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the structure of full-two-dimensional vacuum tube. (Drawing includes non-English language text).
