Fig. 5. Elastic moduli predicted from the core–shell model and experimentally measured results. Circles are calculated by considering the normal mode (n = 2), and crosses are derived using the parametric mode (n = 4). The inset presents the full range modelling from pure Si〈110〉 to pure SiO2 of the core–shell NW. Blue dashed and green dotted lines represent the moduli of bulk Si〈110〉 and SiO2, respectively.
