Unexpected 4 × 4 Charge Density Wave in 1H‑NbTe2 Monolayer

Transition metal ditellurides exhibit structural and electronic properties distinct from their selenide and sulfide counterparts, including the stabilization of multiple charge density wave (CDW) phases. Within the niobium compound family, notable differences in structure are also observed: bulk NbTe2 crystallizes in t...

The Hidden Cost of Alloying: Disorder-Driven Transport Collapse in TMDs

Alloying in two dimensional semiconductors is widely used to tune bandgaps, yet its implications for charge and energy transport remain poorly understood. Here, we investigate MoS2xSe2(1-x) alloys as a model system to study the interplay between composition, thickness, and disorder. Optical transitions and valence band...
