What Does FEES Stand For?

FEES stands for Field Electron Energy Spectroscopy

FEES, or Field Electron Energy Spectroscopy, is an analytical technique used to study the electronic properties of materials at the atomic level. By measuring the energy distribution of electrons emitted from a sample under an applied electric field, FEES provides valuable insights into the surface states and electronic structure of materials. This technique is particularly useful in materials science, nanotechnology, and semiconductor research, enabling the characterization of novel materials and the investigation of fundamental electronic phenomena.
