Abstract

Particulate deposition on Bi film prepared by pulsed laser deposition (PLD) was studied by Rutherford backscattering spectrometry (RBS) using a 2 MeV 4He+ scanning microbeam with a lateral resolution of 2 μm. Droplets and particulate-free areas could be detected and separated in the analysis, which offers the possibility of independent measurement of the chemical composition of the thin film and the micron-sized droplets. Tomographic images illustrated thickness inhomogeneities and cross-sectional thickness profile of particulates and gave more detailed information about the surface topography than the RBS spectra themselves. An example is discussed where thicknesses larger than the probing depth could be measured. This unique combination of possibilities makes micro-RBS a powerful technique for the complete analysis of particulate thin films.
