Perspective carbon materials as electron emitters
Original language description
Carbon materials are good candidates as electron emitters. In this article will be described emission properties of carbon nanotubes prepared by chemical vapour deposition (CVD). The measurement of emission current density flowing through the electrodeswill be carried out in a vacuum chamber pumped by a turbomolecular pump. The vacuum chamber will be equipped with a linear nano-motion drive SmarAct that enables precise changes of the distance between two electrodes inside the vacuum chamber (step widthfrom 50 nm to 1000 nm, sub-nanometer resolution). The measured results will be compared with Fowler-Nordheim theory. One of the proposed solutions for usage CNTs as emitters is in a pressure sensor. A method for packaging emission pressure sensor will be also invented so the emission could exist outside the laboratory vacuum chamber. The electrodes of the sensor could be bonded using glass frit bonding or anodic bonding technology.
