DIFILab hosts a nanofabrication research activity focused on the high-resolution lithography enabled by the novel NanoFrazor instrument.
The Nanofrazor is the first commercial instrument that allows direct surface nanostructucturing, even in three dimensions, via thermal-Scanning Probe Lithography. A nanoscale semiconductor tip is heated up in a controlled way to induce local nanopatterning of a thermo-sensitive material (Fig. 2a, b), also acting as a probe for in-situ imaging of the surface at the nanoscale.
This nanolithography has a strong potential in nanotechnology with impact in optoelectronics, nanophotonics, quantum technologies and biosensing.
