| Abstract: | The process of charged particles transmission through nanoporous alumina membranes with a pore diameter of about 20 nm was studied. A guiding effect was observed for particles passing through dielectric nanocapillaries, which is also typical of glass microcapillaries. The maximum transmission factor measured was 0.625. It was shown in an experiment that Rutherford backscattering is capable of analyzing the quality of the structure of nanoporous membranes. |
