  The electrical conductance and RHEED intensities as a function of the
coverage have been measured during Pb depositions at 105 K on Si(111)-(6x6)Au
with up to 4.2 ML of annealed Pb. The experiments show the strong influence of
used substrates on the behavior of the conductance during the epitaxy of Pb
atoms, especially for very initial stage of growth. Oscillations of the
conductance during the layer-by-layer growth are correlated with RHEED
intensity oscillations. The analysis of the conductance behavior is made
according to the theory described by Trivedi and Aschcroft (Phys.Rev.B 38,12298
(1988)).
