Term: Thermionic Emission

Description:

Thermionic emission refers to the release of electrons from the surface of a heated material. This process occurs when the thermal energy of the material exceeds the work function required for electrons to escape. Thermionic emission plays a crucial role in various electronic devices, such as vacuum tubes and cathode ray tubes.

Sample Sentences:

• The vacuum tube relies on thermionic emission to generate and control electronic currents.
• Thermionic emission is responsible for the electron beam produced in cathode ray tubes, which enables the display of images on old television sets.
• Scientists have been studying ways to enhance thermionic emission efficiency to improve the performance of electronic devices.
