Infrared Pump-Probe Imaging and Spetroscopy with 10nm Resolution

Dear all, Hikami Unit(Mathematical and Theoretical Physics Unit) would like to invite you to a seminar by Dr. Sergiu Amarie. Please see the attached documents. We look forward to seeing many of you there.

- Date: Thursday, July 10th, 2014

Time: 15:30 – 16:00

Venue: C015, Lab1

Speaker: Dr. Sergiu Amarie NeaSpec GmbH, Germany Title: Infrared PUmp-Probe Imaging and Spectroscopy with 10nm Resolution The paper is collaborated with the following authors, Sergiu Amarie1, Martin Wagner2, Michael Goldfla2, Zhe Fei2, Wenzhong Bao4,5, Aleksandr Rodin3, Michael Fogler2, Antonio Castro Neto3, Fritz Keilmann6, Dimitri Basov2; 1Neaspec GmbH, Germany; 2Department of Physics, University of California, USA; 3Department of Physics, Boston University, USA; 4Materials Research Science and Engineering Center, University of Maryland, USA; 5Department of Physics and Astronomy, University of California, USA; 6Department of Physics, Ludwig-Maximilians-University and Center for Nanoscience, Germany. AbstractT We introduce pump−probe sub-diffraction infrared imaging and spectroscopy with 100fs temporal and 10nm spatial resolution. On graphene single-layers, we demonstrate time-resolved access to local optical conductivity at technologically relevant midinfrared frequency.
