A combined laser-based angle-resolved photoemission spectroscopy and two-photon photoemission spectroscopy study ofTd-WTe2

Laser-based angle-resolved photoemission spectroscopy and two-photon photoemission spectroscopy are employed to study the valence electronic structure of the Weyl semimetal candidateTd-WTe(2)along two high symmetry directions and for binding energies between approximate to -1 eV and 5 eV. The experimental data show a good agreement with band structure calculations. Polarization dependent measurements provide further information on initial and intermediate state symmetry properties with respect to the mirror plane of theTdstructure of WTe2.
