In a field emission tube with two probe-holes the cross-correlation functions of current fluctuations from potassium submonolayers on tungsten have been investigated. The measurements were carried out in the temperature range of 290-430 K and with coverages between 0.05 and 0.87. The experimental correlation curves were approximated by a sum of three exponential functions revealing three components with different time constants τ_{i} and amplitudes R. The temperature dependence of the amplitudes R_{2} and R_{3} is discussed in terms of collective flip-flop processes.
