Gas discharge tube with tunnel effect type cathode |
摘要 |
A gas discharge tube using a tunnel effect type electron emitting device as a cathode is provided. The electron emitting device comprises a conductive metal base and a dielectric film formed preferably of a material containing MgO as a main component on the metal base. The dielectric film faces an anode and is exposed to a gas in the tube. In the cathode of this structure, discharge is effected at a relatively low DC voltage.
