New High Energy Scales in Quasi-One-Dimensional K$_{0.3}$MoO$_3$ Revealed by High Resolution Angle-Resolved Photoemission Spectroscopy

ORAL

Abstract

High resolution angle-resolved photoemission (ARPES) measurements have been carried out on K$_{0.3}$MoO$_3$, a proto-typical quasi-one-dimensional material that exhibits Peierls transition at 180 K. Two high energy scales around 100meV and 300meV are revealed in the dispersion measured using super-high resolution vacuum ultra-violet (VUV) laser-based ARPES measurements. These new high energy features emerge in the charge-density-wave state. The origin of these new energy scales will be discussed.
