Abstract: A substrate is provided, which comprises a structured surface including a regular pattern of a plurality of elevated structures that are elevated with respect to a nominal surface of the substrate, wherein at least two dimensions are between 1 nm and 100 ?m, the structured surface being configured to stimulate smooth crystallization of microcrystals or to boost hydrophobic properties. A target plate comprising a plurality of substrates is disclosed as well.
