The growth of thin Cs and K films on Si(111)7 Â 7 kept at 170 K has been followed by second harmonic generation (SHG) during continuous deposition. Initially, both types of alkali atoms adsorb at dangling bond sites, in a similar way as at room temperature. At low temperature the completion of one o
