Probing the Band Structure of LaTe_2 Using Angle Resolved Photoemission Spectroscopy
D. R. Garcia, S. Y. Zhou, G. -H. Gweon +3
With the current interest in the rare-earth tellurides as high temperature charge density wave materials, a greater understanding of the physics of these systems is needed, particu…
Revealing Charge Density Wave Formation in the LaTe_2 System by Angle Resolved Photoemission Spectroscopy
D. R. Garcia, G. -H. Gweon, S. Y. Zhou +5
We present the first direct study of charge density wave (CDW) formation in quasi-2D single layer LaTe_2 using high-resolution angle resolved photoemission spectroscopy (ARPES) and…
Low energy excitations in graphite: The role of dimensionality and lattice defects
S. Y. Zhou, G. -H. Gweon, A. Lanzara
In this paper, we present a high resolution angle resolved photoemission spectroscopy (ARPES) study of the electronic properties of graphite. We found that the nature of the low en…
First direct observation of Dirac fermions in graphite
S. Y. Zhou, G. -H. Gweon, J. Graf +7
Originating from relativistic quantum field theory, Dirac fermions have been recently applied to study various peculiar phenomena in condensed matter physics, including the novel q…
New Luttinger liquid physics from photoemission on LiMoO
Feng Wang, J. V. Alvarez, S. -K. Mo +6
Temperature dependent high resolution photoemission spectra of quasi-1 dimensional LiMoO evince a strong renormalization of its Luttinger liquid density-of-state…
Hidden one-dimensional electronic structure and non-Fermi liquid angle resolved photoemission line shapes of -MoO
G. -H. Gweon, S. -K. Mo, J. W. Allen +4
We report angle resolved photoemission (ARPES) spectra of -MoO, a layered metal that undergoes two charge density wave (CDW) transitions at 109 K and 30 K. We have di…
