After 6K implantation of Si in Pd films, resistivity measurements (previously reported (1)) had provided preliminary evidence that an amorphous state had been reached for a composition Pd.80 SiO 20· This result has been recently confirmed by transmission electron microscopy (TEM) observations : diffuse diffraction rings appear in the implanted part of the Pd film. New experiments are reported : - resistivity dose dependence (and temperature dependence) of a 300K Si implanted Pd film ; - in situ TEM experiments to follow the amorphization process during implantation.
