Emission of low energy electrons from solid surfaces studied by means of spectroscopy with individual as well as correlated electrons

My PhD thesis was focused on studying the secondary electron emission processes in solids with the help of several methods, based on single and double electron spectroscopy. Conventional methods, such as reflection electron energy loss spectroscopy (REELS), time-of-flight spectroscopy (TOF) was used in combination
with secondary electron-electron energy loss spectroscopy and, presented for
the first time, inelastic very low energy electron diffraction (IVLEED) methods.
