This work is a theoretical study of the photoelectron spectroscopy of strongly correlated electron systems. Using exact diagonalization techniques, one-particle excitation spectra of an extended Hubbard model are calculated. Three important issues are investigated systematically. The first is the effects of nonlocal interactions on the spectral redistribution; the second is the coverage dependence of the spectra under various conditions; and the third is the influence of temperature on the spectral evolution. The calculated results and their implications for a wide variety of materials systems are discussed in a many-body picture to gain physical insights.
