摘要：
The potential barrier at the interface between CaF2 and BaF2 layers deposited onto a Si(111) substrate is studied using UPS. It is stated that the evaporation of the BaF2 layer onto a composite CaF2/Si substrate decreases the photoelectron threshold by about 0.5 eV. For the multilayer systems the reversible changes of the photoelectron work function are observed after subsequent film evaporation. © 1990.
