W-based granular metals have been prepared by electron-beam-induced deposition from the tungsten hexacarbonyl W(CO)(6) precursor. In situ electrical conductivity measurements have been performed to monitor the growth process and to investigate the behavior of the deposit under electron beam post-irradiation
