I believe it is tungsten hexacarbonyl (W(CO)6)

In this study we investigate the nucleation and growth mechanisms of tungsten films processed by focused ion beam (FIB) induced chemical vapor deposition. For our investigation we use a 50keV Ga+ ion beam focused on the substrate target and tungsten hexacarbonyl (W(CO)6) as precursor gas.

any process related document on W(CO)6 depostion using FIB

better the carbon is best or ?
