Electronic Structure of ZrTe3 from Angle-Resolved Photoemission Spectroscopy
ORAL
Abstract
ZrTe$_{3}$ has both quasi-one dimensional and quasi-two-dimensional structural components in its crystal structure. It shows not only charge density wave (CDW), but also deserves studying the coexistence or competition between different broken-symmetry ground states. In this talk, we will present electronic study on ZrTe$_{3\, }$by angle-resolved Time-of-Flight electron analyzer that can cover two-dimensional momentum space simultaneously with high energy (\textasciitilde 1meV) and momentum resolution, Bilayer splitting feature is clearly resolved and its momentum and temperature dependence is investigated. We will discuss on the CDW ground state and the normal state quasi-particle formation in ZrTe$_{3}$ based on our measurements.
