• dielectric materials such as the glass and silicon is inevitably missing. 2) The foci at the air/silicon and air/glass interfaces are different due to the different material properties. 3) This simple convolution approach accurately describes the scattering at single nanostructures but completely neglects

• -dimensional finite-difference time domain (3D-FDTD) simulations [20]. A metal substrate such as gold provides an additional field enhancement as it produces a large electromagnetic (EM) coupling with the tip, which is often called a “gap mode”. In contrast, dielectric materials cannot couple as effectively

• is necessary and the substrates must be able to withstand this etching procedure. In this context, among dielectric materials especially, oxides such as MgO, sapphire, SrTiO3, quartz were found to be suitable, as well as materials forming thin oxide layers such as Si. Furthermore, adhesion of the NPs
