EPR Spectroscopy: Useful Tool for Analyzing Electronic Structure of Materials
Giorno 13 settembre 2022, con inizio alle ore 10:00, presso l'Aula T del DFA, su invito del Prof. S. Mirabella, il Prof. Emre Erdem (Sabancı University, Turkey) terrà un seminario dal titolo EPR Spectroscopy: Useful Tool for Analyzing Electronic Structure of Materials.
Tutte le persone interessate sono invitate a partecipare.
Abstract. Electron paramagnetic resonance (EPR) is a very powerful method due to its enhanced sensitivity to unpaired electrons. In this talk tthe basics necessary for understanding how the EPR signal arises are presented. The concept of magnetic resonance is introduced and the aspects which influence the EPR spectral shape, isotropy/anisotropy, relaxation effects, interactions with other electron and nuclear spins, are discussed. Crystal field, quadrupole terms, Zeeman effect will be discussed in the vicinity of spin-Hamiltonian energy terms. Advantages of high-/multi-frequency EPR spectroscopy will be introduced. Some important applications of EPR will be given as well.
Bio. Emre Erdem is now associate professor at Sabanci University, Materials Science and Nano Engineering program (Istanbul / Turkey). He obtained his BSc degree from Ankara University Physics Department in 1998. In 2001 and 2006, he received his MSc and Ph.D. Degrees from the University of Leipzig Physics Department, respectively. He did postdoctoral research at the Technical University of Darmstadt between the years 2006-2009. In 2010, he became a research group leader in University of Freiburg on the spectroscopic studies of functional nanomaterials and in 2017 he received his habilitation degree in Physical Chemistry. He was awarded LE STUDIUM / Marie Skłodowska-CurieResearch Fellowship (2017), Eugen Grätz Prize (2011) and DAAD scholarship (1999). He (co-)authored more than 100 publications in international journals and more than 50 invited talks in conferences. He is Editor-in-Chief of the journal Experimental Results and Associate Editor in Scientific Reports.
