Abstract A recently developed embedded cluster scheme is applied to study the coverage dependence of charge transfer between Cs and the (001) surface of all 5d transition metals, which agrees with the jellium-slab model calculation given by the first principle band method. The correlation between the initial drop of work function during cesiation caused by this charge transfer and the unfilled d band of the substrates is revealed
