We have stabilized and equalized field-emission (FE) currents from carbon nanotube (CNT) emitters by a cascade active-current-control (ACC) using two transistors. Theoretical and experimental analyses on the cascade ACC operation, including single AC

We developed a fully closed nano-focus X-ray source using carbon nanotube (CNT) field emitters. The nano-focus X-ray source includes a fully vacuum-sealed CNT Electron-gun (E-gun) tube and E-beam-focusing modules consisting of electrostatic and magne

Vertically aligned CNTs were synthesized on a four inch wafer, followed by the preparation of a CNT yarn. The yarn emitter was found to have an extremely high field enhancement factor, which was confirmed to have originated from multi-stage effect. I
