We explore novel top-down methods to fabricate nanostructures and devices, as well as utilizing self-assembly approaches, with the aim to realize atomic level control.

Scanning Electron Microscopy top view of InAs vertical nanowires grown InAs/Si substrate by a selective area epitaxy with SiNx as a mask. The silicon nitride mask was patterned by a Block-Copolymer (BCP) lithography using hexagonally-oriented, vertical cylinders formed in a 50 nm pitch PS-b-P4VP polymer system.
