SOR Seminar: Angle-Resolved Photoemission Spectroscopy at Diamond Light Source, the example of quasi-one dimensional Tl2Mo6Se6
標題: SOR Seminar: Angle-Resolved Photoemission Spectroscopy at Diamond Light Source, the example of quasi-one dimensional Tl2Mo6Se6
日時: 2016年4月4日(月)  午後2:00~
場所: 物性研究所本館6階 第1会議室(A636)  SPring-8会議室(TV会議)
講師: Dr. Moritz Hoesch
所属: Diamond Light Source
要旨: A beamline for high-resolution angle-resolved photoelectron spectroscopy (ARPES) has been built at Diamond light Source in the United Kingdom.
The full extent of the project will consist of two instruments, nano-ARPES that is currently under commissioning, and high-resolution HR-ARPES that started full operation in January 2014.In this seminar I will describe the implementation of HR-ARPES and its extended sample preparation facilities and gives a few examples of research that has been conducted.

 As a particularly interesting case study I will present data from  quasi-one-dimensional Tl2Mo6Se6 where a survey of momentums spaces reveals an indeed highly one-dimensional Fermi surface and peculiar reduction of intensity near E_F that will be discussed in the context of Tomonaga-Luttinger liquid theory.
