The heat causes thermionic emission of electrons into the vacuum.

In 1880 he discovers thermionic emission or the Edison effect.

Frederick Guthrie is the first to report observing thermionic emission.

The other relies on vacuum tubes and the principles of thermionic emission.

Thermionic emission can also be enhanced by interaction with other forms of excitation such as light.

Derivations of thermionic emission equations from an undergraduate lab, csbsju.edu.

Thermionic emission can be used to measure the work function of both the hot emitter and cold collector.

This can be accomplished by e.g. thermionic emission or arc discharge.

When hot, the filament releases electrons into the vacuum, a process called thermionic emission.

This one-way current was called the Edison effect (although the term is occasionally used to refer to thermionic emission itself).

How vacuum tubes really work with a section on thermionic emission, with equations, john-a-harper.com.

The thermionic emission of electrons is also known as thermal electron emission.

His research on thermionic emission is remembered in the form of the Richardson-Dushman equation.

When the excitation over the barrier is thermal, the process is called thermionic emission.

The heat knocks electrons out of the electrodes by thermionic emission, which helps maintain the arc.

This is called thermionic emission.

Thermionic emission is the heat-induced flow of charge carriers from a surface or over a potential-energy barrier.

The current through the filaments causes them to heat up and emit electrons into the tube gas by thermionic emission.

In Bethe's theory, the current is limited by thermionic emission of electrons over the metal-semiconductor potential barrier.

Applying the field causes lowering of the barrier, and thus enhances the emission current in thermionic emission.

A variety of effects can be harnessed to produce thermoelectricity, thermionic emission, pyroelectricity and piezoelectricity.

When the heater is energized, the heating coil will cause electrons to emerge from it due thermionic emission.

When the light is turned on, the electric power heats up the cathode enough for it to emit electrons (thermionic emission).

Electrons are emitted from the barium oxide impregnated insert by thermionic emission.

Many of the ionized xenon atoms are accelerated into the walls where their energy maintains the thermionic emission temperature.
