Experiment Topics: ..
The following topics can be discussed with this highly evacuated tube: 
•  Edison-Richardson-Effect, thermionic emission
•  Diode characteristics, space charge region, Schottky-Langmuir law
•  Diode rectifier

Product Information: ..
The diode is a highly evacuated tube with a pure tungsten heater filament (cathode) and a circular metal plate (anode) inside a clear glass bulb. The cathode filament and the anode plate are parallel to one another. This planar configuration corresponds to the conventional symbol for a diode. A circular metal plate mounted behind the filament ensures that the electric field between the anode and cathode is uniform.
The diode allows basic experiments to be performed on the Edison effect (thermionic effect), demonstrates how the emission current depends on the power supplied to heat the hot cathode, allows recording diode characteristics and shows the use of the diode as a rectifier.
