ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,463,002, issued on Nov. 4, was assigned to NCX Corp. (Raleigh, N.C.).
"Energy tuner for a gated field emission cathode device, and associated method" was invented by Jian Zhang (Durham, N.C.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A field emission cathode device includes a cathode element having a field emission surface and an adjacent gate electrode element defining a first gap therebetween. A gate voltage applied to the gate electrode element causes the field emission surface to emit electrons that are accelerated through the gate electrode element. The gate electrode element is disposed between the cathode element and an anode element, the anod...
