Nanoscopic materials response to radiation and corrosion environments

In this thesis, computational and experimental techniques are developed to study the response of materials to radiation and corrosion environments at nanoscale, respectively. Firstly, controlled ion radiation has become a popular tool for the fabrication and modification of nanostructured materials as well as understanding materials degradation in radiation environment. Here we aim to overcome a major limitation in current 1D Monte Carlo simulation codes for ion radiation, i.e., the incapability to predict the primary radiation damage in nanoscale ion implantation experiments. A prototype code in MATLAB named "Mat-TRIM", and a more advanced code in C-language named "IM3D", are developed to accurately capture the key physics of ion-mater interaction in nano-structured materials in three-dimensions (3D). Using IM3D, we revealed the nano-beam and nano-target effect of ion radiation.
