LADP-14 Determining Specific Charge of Electron

Determining Specific Charge of Electron  Determining Specific Charge of Electron is designed to determine the specific charge. Main parameters Filament current Anode voltage Anode current Excitation current 0-1.000A 0-150.0V Resolution 0.1μA 0-1.000A Standard configuration Electronic power tester, ideal diode, excitation coil, data processing software. Experiments 1.Use Richardson straight line method to measure the work of metal electrons. 2.Measuring zero field current by epitaxial method. 3.Use the magnetic control method to measure the charge mass ratio of the electron. 4.Measuring Fermi Dirac distribution. 5.Measure Fermi energy level.                        Ia-Is Curve
