In the literature there are many suggested surface structures to be used as SERS substrates. Novel materials and geometries are also constantly being developed, focusing on higher yield, cheaper manufacturing and easier use. | In the literature there are many suggested surface structures to be used as SERS substrates.

+ | Here we show an example of the calculation setup for a SERS substrate on a bit more complex geometry, inspired by work in Ref. 1. This is based on flexible gold coated silicon nanowires. By different manufacturing conditions, the level of self-organisation of the top spheres and their geometrical properties can be controlled. Using GSvit we tried to setup models that would | ||
