The growth of silver deposited on the GaAs(001)-(2x4) surface has been investigated via scanning tunneling microscopy (STM). Silver aggregates in the Volmer-Weber mode, forming hut-shaped islands whose average dimension increases according to the power law Θ 1/z , with z~1.5 and Θ being the number of silver atoms deposited at constant rate on the substrate. We found that 80% of the...
