Observation of Dirac-like band dispersion in LaAgSb
X. Shi, P. Richard, Kefeng Wang +10
We present a combined angle-resolved photoemission spectroscopy (ARPES) and first-principles calculations study of the electronic structure of LaAgSb in the entire first Brillo…
Raman study of lattice dynamics in Weyl semimetal TaAs
H. W. Liu, P. Richard, Z. D. Song +4
We report a polarized Raman study of Weyl semimetal TaAs. We observe all the optical phonons, with energies and symmetries consistent with our first-principles calculations. We det…
Raman scattering investigation of large positive magnetoresistance material WTe
W. -D. Kong, S. -F. Wu, P. Richard +5
We have performed polarized Raman scattering measurements on WTe, for which an extremely large positive magnetoresistance has been reported recently. We observe 5 A phonon…
Experimental discovery of Weyl semimetal TaAs
B. Q. Lv, H. M. Weng, B. B. Fu +11
Weyl semimetals are a class of materials that can be regarded as three-dimensional analogs of graphene breaking time reversal or inversion symmetry. Electrons in a Weyl semimetal b…
