Description
Abstract:
In my presentation, I will introduce the working principle of infrared and terahertz scattering-type scanning near field optical microscopy (s-SNOM) and spectroscopy. Two of my representative experiments with IR s-SNOM on the insulator-to-metal phase transition of correlated electron materials Ca2RuO4 and VO2 will be talked about. I will then demonstrate optical pump terahertz near-field probe (n-OPTP) and optical pump terahertz near field emission (n-OPTE) experiments on graphene and InAs.
