Nanofabrication Research Group

Welcome

The Nanofabrication Research Group develops novel nanofabrication and nanomanufacturing techniques and the enabling measurement methods.  The Group uses a combination of theory, simulation and experiment to measure the fundamental processes underlying both top-down and bottom-up nanofabrication, and to thereby work towards feasible approaches for high-volume nanomanufacturing.  Experts in plasmonics, photonics and metamaterials are creating new ways of controlling light far below the diffraction limit for observing and manipulating nanostructures.  Micro- and nano-electromechanical systems are being developed as multi-probe platforms for rapid nanofabrication and multi-mode characterization of materials and devices.  Stochastic processes — ubiquitous at the nanoscale — are being harnessed for precise and accurate control of nanostructure position and orientation during bottom-up assembly processes.
