WebTaAs single crystals using ARPES. The core-level spec-trum in Fig. 1(e) shows the characteristic peaks of Ta and As elements, confirming the chemical composition of TaAs samples. It is important to notice that the As 3d core levels have two sets of spin-orbit doublets, while the Ta 4f core levels have only one set of doublets,

WebWe combine quasiparticle interference simulation (theory) and atomic resolution scanning tunneling spectro-microscopy (experiment) to visualize the interference patterns on a type-II Weyl semimetal MoxW1−xTe2 for the first time. Our simulation based on first-principles band topology theoretically reveals the surface electron scattering behavior. We identify the … WebJun 2, 2024 · Below, we will focus on presenting our angle-resolved photoemission spectroscopy (ARPES) data on LaAlGe and show how these data demonstrate type II Weyl fermions without relying on the agreement with theoretical calculations. Figure 2A shows the measured kz − kx Fermi surface contours of the bulk bands on the ky = 0 plane.
