What Does SPIES Stand For?

SPIES stands for Surface Penning Ionization Electron Spectroscopy

SPIES, or Surface Penning Ionization Electron Spectroscopy, is an analytical technique utilized to study the electronic properties and surface composition of materials. By leveraging Penning ionization, SPIES facilitates the detection and characterization of low-energy electrons emitted from surfaces, allowing researchers to gain insights into surface interactions, chemical states, and material behavior at the atomic level. This method offers high sensitivity and specificity, making it a valuable tool in material science, surfaces chemistry, and nanotechnology research.
