论文摘要
基于激光的角度分辨光谱光谱（ARPE）和两光子光发射光谱（2PPES）用于研究Weyl Semimetal候选TD-WTE $ _2 $沿两个高对称性方向的Weyl Semimetal候选$ _2 $的价电子结构，用于$ \ \ $ \ $ \ $ \ $ \ $ \ $ -1 EV和5 ev和5 ev。实验数据表明，与频带结构计算有很好的一致性。相对于WTE $ _2 $的TD结构的镜面平面，相对于初始状态和中间状态对称属性提供了偏振相关的测量。
Laser-based angle-resolved photoemission spectroscopy (ARPES) and two-photon photoemission spectroscopy (2PPES) are employed to study the valence electronic structure of the Weyl semimetal candidate Td-WTe$_2$ along two high symmetry directions and for binding energies between $\approx$ -1 eV and 5 eV. The experimental data show a good agreement with band structure calculations. Polarization dependent measurements provide furthermore information on initial and intermediate state symmetry properties with respect to the mirror plane of the Td structure of WTe$_2$.
