Professor Philomela Komninou Seminar
May 16, 2017 @ 2:00 pm - 3:00 pm
Professor Philomela Komninou, from Aristotle University of Thessaloniki, Greece, will be presenting a seminar titled, “Investigating Materials Structure at the Nanoscale.”
Electron Microscopy Laboratory, Department of Physics
Aristotle University of Thessaloniki, GR-54124 Thessaloniki, Greece
New technologies make use of advanced nanostructured materials and systems which are mainly fabricated on non-equilibrium conditions and present superior physical or mechanical properties. Many of these systems are 1 -, 2- and 3-dimensional as nanowires, quantum wells, quantum dots and nanoparticles. Control of the structure of these materials down to nanometer scale and interfacial engineering have shown that local atomic structure plays a crucial role in the mechanisms responsible for new phenomena observed and new properties measured. Therefore, prior of any effort to develop models explaining phenomena and properties, the investigation of their real microstructure is a prerequisite. The transmission electron microscope (TEM) is the instrument of choice and the technique of atomic resolution transmission electron microscopy, known simply as high resolution transmission electron microscopy (HRTEM), has become increasingly important.
The aim of the talk is to present detailed information on the structure of a range of material systems at the atomic scale by means of transmission electron microscopy, to elucidate the correlation between growth and structure of nanomaterials and to understand nano-mechanisms that tailor properties.
