Condensed Matter Seminar Series
Nanoscale Mechanical Studies using Atomic Force Microscopy
UNC Chapel Hill
Thursday March 1, 11:30 am, Room 298, Physics Building
Force measurement capability down to the picoNewton range with AFM and other techniques has enabled investigations of the mechanical properties of a wide range of systems, from nanoelectromechanical systems to proteins and cells. I will review our progress in fabricating and mechanically characterizing carbon nanotube based resonators. Very recent results showing modulation in electronic transport through single wall tubes due to mechanically induced torsion will be discussed. I will also review other work investigating biological systems, including progress on mechanical evaluation of fibrin fibers. We have found these fibers exhibit unusually high extensibility.
