Description

Electron emission is when electrons escape from the surface of a material. Emissions can be caused by many different mechanisms such as thermionic effects, photon, electron, or ion radiation. When energy is imparted to a material, it can cause electron emissions. Emitted electrons have an energy distribution or emission spectra. Figure 1 shows the emission spectra of gold when irradiated with an ~80 eV electron beam. Emission spectra are related to the work function for metals or the electron affinity for insulators. The goal of this research is to measure the work function or electron affinity of a material using electron yield decay curves.
