Electron-stimulated desorption of potassium atoms from a potassium layer adsorbed on a tungsten covered with a gold film

Abstract

Abstract For the first time, electron-stimulated desorption (ESD) of K atoms from the K layer adsorbed on W covered with an Au film was detected and recorded, and the ESD yield was measured by a direct method depending on the electron energy, concentration K, and the thickness of the Au film. A model is proposed that explains the processes of ESD of potassium atoms from the surface.
