(PhysOrg.com) -- As technology shrinks ever smaller, interest in objects and devices on the nanoscale becomes more apparent. However, visualizing these objects in three dimensions comes with special challenges. Alexander Govyadinov, a scientist at the University of Pennsylvania, points out that imaging nano-objects in 3-D typically requires measurements of the optical phase, a task which is so difficult that it is rarely done. http://www.physorg.com/news178870057.html Physics Tue, 01 Dec 2009 08:30:02 EST news178870057 (PhysOrg.com) -- A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. The method, which is based on near-field microscopy, opens new avenues for analyzing mechanical properties of high-performance materials or for contact-free mapping of local conductivity in strain-engineered electronic devices (Nature Nanotechnology, advanced online publication, 11 Jan. 2009). http://www.physorg.com/news151930864.html Nanotechnology Fri, 23 Jan 2009 11:01:37 EST news151930864 (PhysOrg.com) -- A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors.
