John, N.R. Selvi, G.U. Kulkarni, S. Heun, E. Cavaliere, M. Fanetti, I. Kholmanov, L. Gavioli, M. Sancrotti] Cup-like structures of In, Sn and Nb on Si substrates with femtoliter capacity obtained by pulsed laser ablation, have been subjected to different oxidation treatments and examined employing spatially resolved scanning Auger spectroscopy and microscopy (SR-AES and SAM). The as-prepared cups, when exposed to ambient conditions are found to have a native oxide layer at the surface that could be easily removed by Ar ion sputtering, resulting in clean metal cups, suitable for functionalization. In the case of In cups, the thin metal layer at the bottom of the cups could be easily removed by sputtering to form In rings. Cups subjected to an external oxidation treatment have a thicker oxide layer in comparison to in-situ dosing of oxygen. In the case of Nb cups, the high temperature treatment employed during oxidation resulted in the segregation of Si to the surface of the cups. There is also evidence for the formation of a metal-silicon alloy at the center of the cups, especially in the case of Sn and Nb, during the oxidation treatment at elevated temperatures.
