光FORUM 平成25年度第2回セミナー 開催のお知らせ
光FORUMの平成25年度第2回セミナーを以下の日程で開催します。
日時：2014年3月13日（木）13:30～15:00
場所：理学部4号館1320号室
講演者： Professor Frank Hegmann (Department of Physics, University of Alberta)
講演題目: Nanoscale ultrafast terahertz dynamics in semiconductors
講演要旨
Time-resolved terahertz pulse spectroscopy is a powerful tool for
probing ultrafast carrier dynamics and the nature of carrier transport
in nanostructured materials. This talk will provide an introduction to
terahertz (THz) pulse spectroscopy, discuss how it can be applied to
reveal ultrafast dynamics over nanometer length scales in materials,
and present a new technique that couples THz pulses to the tip of a
scanning tunneling microscope (THz-STM) and can directly image
sub-picosecond carrier capture into a single semiconductor nanodot.
