Resumen:
High-energy ion tracks (374 MeV Au26+) in thin films were
examined with transmission electron microscopy to investigate nanopore
formation. Tracks in quartz and mica showed diffraction contrast. Tracks
in sapphire and mica showed craters formed at the positions of ion
incidence and exit, with a lower-density track connecting them. Direct
nanopore formation by ions (without chemical etching) would appear to
require film thicknesses less than 10 nm.
