Multi-axial Evaporation trhough Nano-Hole Masks: a 3D-printer for the nanoscale

Abstract

Nowadays we are witnessing breakthrough discoveries in science that improve our understanding of nature and put forward promising practical realizations. These discoveries very often benefit from nanofabrication techniques that allow obtaining sophisticated materials systems whose properties can be designed by structural and compositional control atdavid the nanoscale, making possible the exploration of novel physical phenomena unattainable up to day. Light-matter interaction is not an exception of this and, for example, magnetic field control and enhancement of this interaction have been demonstrated in nanosystems where building blocks with plasmonic and ferromagnetic properties coexist [1]. To give an example, by embedding a ferromagnetic nanodisk in a plasmonic ring and locating it below the hot spot of a plasmonic split ring, a three fold enhancement of the magnetooptical activity of the system can be achieved [2].
