Two Possible Measurements of the Effective Mass of Electrons Injected Into a Liquid
The experiments that are proposed aim at the measurement of the effective mass of an electron injected into an insulating liquid by either studying the modulation of the photoemission from a semiconductor into a liquid when a large magnetic field is applied to the photocathode or the absorption of f.i.r. radiation by electrons trapped in a potential well near the surface of the liquid. In the former case the modulation should be periodic in 1/B and, depending on the initial electron states in the photocathode, should appear as either a series of steps or a series of maxima in the photoelectric yield. From the separation of these steps the effective mass of the electrons can be calculated. In the latter type of measurement the electrons are trapped in a potential well near the surface by a combination of their image charges and an external electric field. Both the depth of the well and the energy levels in the well depend on both the external electric field and the electron effective mass.
