China Wholesale Liquid Conductivity Manufacturers – LEEM-5 Apparatus of Work Function & Specific Charge of Electron – Labor Detail:
Description
Thermionic emission, one of its founders was Owen W. Richardson (1879～1959), a famous physicist in England, who discovered the thermionic emission law, namely Richardson law, pointing out the way for designing reasonable electron emission mechanism. His study had a profound impact on development of radio electronics, and won the 1928 Nobel Prize in Physics as a result.
Functions
1. Understand the concept of thermionic electron emission and verify the Schottky effect
2. Understand the concept of work function of a metal
3. Learn how to measure metal work function based on Richardson straight-line method
4. Understand magnetron principle and determine charge-mass ratio (e/m) by magnetron
