Abstract
The cross-correlation functions (CCFs) of the field emission flicker noise across the W(112) plane were measured with constant potassium submonolayers deposited onto different preadsorbed nickel doses. In general, the CCFs show a distinct maximum with increasing delay time τ. The delay times τmax corresponding to the maximum of the CCF are exponentially increasing with increasing reciprocal temperature. The nickel coverage dependence of τmax reached a deep minimum at a nickel coverage corresponding to the work function maximum of the Ni/W (112) system. A preliminary interpretation is given.
