On the flat: Patterned surfaces without any topographic features are prepared by a modified template-stripping procedure. Their heterogeneous nature is revealed by the AFM phase contrast between gold and silicon dioxide areas (see image). Straightforward assembly of patterned, multifunctional monolayers paired with their ultralow surface roughness makes these surfaces attractive substrates for any monolayer-based device.
