    Ted Pella thin suspended si 3 n 4 membranes
    Size-selected Pt n cluster generation, deposition and transport on silicon nitride and silicon oxide supports. (a) Scanning the mass-to-charge ratio via the quadrupole mass filter gives a mass spectrum with an intense peak for Pt atoms and separate peaks for Pt n ( n = 2, 3, 4, … 31) clusters. (b and c) Pt 20 clusters deposited onto the 8 nm thin Si 3 N 4 membrane of a TEM grid imaged via HAADF-STEM (b) before and (c) after transport from Munich to Berkeley in air, XPS measurements in oxidizing and reducing atmospheres and transport back to Munich. (d) Pt 4f region of Pt n /SiO 2 /n-Si(100) samples with n = 8, 12, 13, 14, 20 and 40 atom clusters. The black vertical line is a guide to the eye, illustrating the binding energy size dependence. (e) C 1s region of a SiO 2 /n-Si sample taken at 490 eV during sample cleaning in 0.7 mbar O 2 at 393 K, at the beginning of the treatment (black) and after 20 min (red). (f) Representative Si 2p spectrum and fit.

    Article Snippet: For checks of Pt n cluster size via scanning transmission electron microscopy (STEM), clusters were deposited onto TEM grids with 8 nm thin suspended Si 3 N 4 membranes (TedPella, layout see SI, Fig. S2), using a hot filament in the vicinity for charge compensation on the sample.
