The electron-stimulated desorption of lithium and potassium atoms from LixAuy and KxAuy layers on the surface of gold adsorbed on W(100) has been studied. The yield of electron-stimulated desorption of Li and K atoms was  measured by a direct method as a function of the electron energy, the concentration of Li and K atoms, and the thickness of the Au film. The formation of semiconductor intermetallic compounds LixAuy and KxAuy is considered.
