Local melting of the NiAl-substrate under deposited Pd-clusters during electron irradiation in a transmission electron microscopeNepijko, S. A.; Klimenkov, M.; Kuhlenbeck, H.; Freund, H.-J.
We have shown that holes with diameters in the nanometer range may be created in the Al2O3/NiAl(110) substrate if metal clusters deposited on it are irradiated by the intense convergent electron beam in TEM. The localisation and size of holes can be controlled to some extend. The formation of holes can be interrupted by lowering the beam intensity below a critical value. It can be continued by increasing the intensity above the threshold value. We have also disclosed the necessity of clusters' presence on the surface for the start of holes' formation.
