제목: Optical spectroscopic probe on the surface state in three dimensional topological insulators
연사: 이 윤 상 교수님 (숭실대학교) 일시: 2012. 11. 5(월) 오후 4시 장소: 물리학과 2층 라운지세미나실
heart of the current condensed matter physics field, featuring the
spin-momentum-locked gapless surface states which give rise to
interesting quantum phenomena possibly related to spintronics. Because
the intriguing surface state for TIs is confined to a few surface
layers, it is hard to address in conventional light-probing methods.
In this presentation we will introduce our ongoing research on several
three dimensional TIs by using magneto-optics and THz spectroscopy.
