Theme 2: Nanometer-scale light-matter interactions

Coordinator ">Guillaume SCHULL (IPCMS, Strasbourg)

Objectives

  • Towards an optical microscopy at the nanometer scale
  • Combination of STM spatial resolution (Å) and Pump-probe techniques time resolution (fs)
  • Study of photoactivated processes

Experimental ressources

Low temperature STM (77K, 4K, or <4K) coupled with a dectection and/or an optical excitation
