The helium ion microscope (HeIM) holds immense promise for nano-engineering and
imaging with scope for in-situ chemical analysis. Here we will examine the potential of …

Mixed halide (I/Br) complex organic/inorganic hybrid perovskite materials have attracted
much attention recently because of their excellent photovoltaic properties. Although it has …

The nano-scale dispersion of ordered/disordered phases in semi-crystalline polymers can
strongly influence their performance eg in terms of mechanical properties and/or electronic …

We report results of ion neutralization of low-energy positive He ions interacting with a
surface of highly oriented pyrolitic graphite as a function of the impinging energy. We found …

At keV energies, many electronic processes contribute to the emission of secondary
electrons in the interaction of highly charged ions on surfaces. To unravel contributions …

Materials engineers have increasing control over nanoscale chemical composition and
nanostructures. The latter can be easily analysed by the scanning electron microscope …

Engineering the properties of materials through defects is at the forefront of research in
Materials Science. Here, we investigate the defects produced on highly oriented pyrolytic …

This dissertation is submitted to Loughborough University in partial fulfilment for the degree
