abstract = {Charge density waves (CDWs) are a canonical
interaction-driven electronic phenomenon with potential
technological applications, such as collective electronic
switching and local information storage. Here, we
investigate the properties of the CDW in the mixed-chalcogen
compound 1T-TaSeTe using bulk- and surface-sensitive
diffraction and spectroscopy techniques and transport
measurements. Compared to the pristine parent compound
1T-TaSe2, we find that the incommensurate CDW appears to
remain incommensurate down to low temperatures. The
CDW-induced gapping of the Fermi surface is pronounced and
may explain the observed semiconductor-like electrical
resistivity behavior in combination with chalcogen disorder.
Our results demonstrate that disordered chalcogen
substitution doping can modify, yet preserve, the
characteristic emergent electronic properties of a
transition metal dichalcogenide.},
