Progress in nanotechnology depends on the capability to fabricate, position, and interconnect nanometer-scale structures. The Speaker will present recent results about thermochemical nanolithography, also called thermochemical scanning probe lithography (tc-SPL), invented in her laboratory at Georgia Tech in 2007. tc-SPL uses a hot nano-tip to activate and “pattern” chemical reactions with nanoscale precision with the ultimate goal of nanofabricating a large variety of materials. The speaker will overview applications in patterning graphene-like nanowires in graphene oxide, piezoelectric ceramic wires on plastic, proteins/DNA arrays with 10 nm-resolution, concentration gradients of proteins with sub-100 nm resolution, and magnetic nanopatterns for spin-waves devices. Finally the Speaker will discuss how tc-SPL can pattern high performance electrodes and doping in 2D materials, achieving better devices compared to e-beam
Biography: Professor Elisa Riedo received her B.S. in Physics from the University of Milano, Italy in 1995 with Summa Cum Laude. In 2000, she received her Ph.D. in Physics in a joint program between the University of Milano and the European Synchrotron Radiation Facility in Grenoble, France. For four years, she has been a Post Doctoral Fellow at the EPFL in Lausanne working on the origin of nanoscopic friction. From 2003 to 2015 she has been a Professor of Physics at the Georgia Institute of Technology. Since Fall 2015, she is a new faculty at the Advanced Science Research Center (ASRC), as well as a Physics Professor at City College. At the ASRC, she is the director of the picoForce Laboratory, which develops new scanning probe microscopy based methods to study the properties of materials at the nanoscale and for nanomanufacturing advanced nano-materials. In 2013, Dr. Riedo was elected APS Fellow, in the Division of Condensed Matter Physics, for her atomic force microscopy studies of nanoscale friction, liquid structure and nanotube elasticity, and the invention of thermochemical nanolithography.
