With this in mind, we propose two fabrication routes to obtain periodic structures comprising arrays of nanocavities in metal films. Both techniques are

Applied in this way, the method is a direct extension of the seminal work by Fischer and Zingsheim on hexagonal ordered arrays of polystyrene colloids serving as masks for subsequent metal evaporations [1]. In other cases, based on precursor

In this way, hexagonal ordered arrays of metal nanoparticles can

• , dewetting of polycrystalline metallic films on a flat substrate usually leads to a broad distribution of particle size and spacing. On the other hand, dewetting of metallic films on pre-patterned substrates can lead to the formation of ordered particle arrays. Formation of 2D ordered arrays of nanoparticles

The as-prepared particles, however, are in most cases partially disordered and can also contain twin planes [4]. In the past, major attention has been paid
