Band-structure effects in secondary-electron-emission and absorbed-current spectra of (111), (100), and (110) surfaces of silver
Abstract
We have measured absorbed-current and secondary-electron-emission spectra in normal incidence and emission, respectively, from the (111), (100), and (110) surfaces of silver. The main features below 10 eV electron energy show good agreement with the bulk band structure for wave vectors normal to the surfaces. Structures due to surface-plasmon threshold energies are not observed. We conclude that the absorbed current is mainly determined by the elastic part of the total electron reflectivity, at least in the energy range investigated here. © 1990 The American Physical Society.
