Novel phenomena in surface physics and the behaviour of stacking fault tetrahedra (SFT) generated in electron irradiation of the face-centred-cubic (FCC) metals Au, Ag and Cu at low temperatures, which have been found recently with HRTEM in Stuttgart, are summarized. The novel phenomenon on the bottom surface, viz, the formation of aligned nanogrooves and deep nanoholes, was first found for thin (001) gold foils irradiated with high doses of 360–1250 keV electrons at temperatures of about 100 K. The pattern depends both on the surface orientation and irradiation direction. The patterns of nanogrooves on silver and copper surfaces, on the other hand, are rather different from that of gold. Also interesting phenomena on the behaviour of SFT were found for these metals irradiated with 1.25 MeV electrons at temperatures between 110 and 350 K. In both Cu and Ag, after prolonged irradiation, voids appear close to SFT formed earlier. For Au a cooperative collapse of SFT lattices to large loops was found.
