thermionic diode meaning

• [Electronics]
  A hot-cathode diode tube.
  

• A high power microwave detector based on thermionic diode
• Bell Labs did not develop a satisfactory thermionic diode for microwave reception.
• A thermionic diode is a plate ( anode ).
• In 1904, John Ambrose Fleming invented the thermionic diode, the first kind of vacuum tube.
• The same year John Ambrose Fleming invented the Fleming valve or thermionic diode which could also rectify an AM signal.
• He invented the thermionic diode 1873 ( this was later given alternate credit to Edison's assistant WJ Hammer ).
• These helicopters exhibited an excess lifting capability sufficient to carry a lightweight receiving antenna and a close-spaced thermionic diode rectifier . ""
• Energy level diagrams for thermionic diode in " forward bias " configuration, used to extract all hot electrons coming out from the emitter's surface.
• The thermionic diode can also be configured as a device that converts a heat difference to electric power directly without moving parts ( a thermionic converter, a type of heat engine ).
• These in turn were replaced by the crystal detector around 1906, and then around 1912 by vacuum tube technologies such as John Ambrose Fleming's thermionic diode and Lee De Forest's Audion ( triode ) tube.
