• using various dry/wet etching techniques including electrochemical HF etching, stain etching, metal-assisted etching, and reactive ion etching [9][11]. So-called “nanograss” or “black silicon” is a surface modification of silicon where the surface is covered with millions of tiny needle-like structures

• exceeding the maximum pressure allowed in the SEM chamber (approximately 10−4 mbar). A silicon substrate was used for all deposition experiments, patterned such that circular areas of pristine silicon are surrounded by black silicon (obtained by reactive ion etching). The black silicon area aids in focusing

• geometry of the self-assembled structures in a wide range. This includes high aspect ratio silicon nanowires (so-called black silicon) with an average reflectance of less than 0.5%. The etching mechanism can also be optimised by the selection of the noble metal. The usage of gold will lead to straight
