Description
Transition Metal Dichalcogenides (TMDs), a key class of 2D quantum materials, are emerging as promising alternatives to enhance efficiency at the same length scale as silicon-based electronics. Among them, WTe₂ stands out for its unique bulk properties, including its topological semimetal behaviour, the type II Weyl fermions it hosts, and its exceptionally large magnetoresistance.
We investigate cleaved bulk WTe₂ using a scanning tunneling microscope (STM) at 330 mK, combining with scanning tunnelling spectroscopy to probe its electronic properties and their dependence on vector magnetic fields. By applying sparse sampling techniques, we resolve new QPI wavevectors in WTe₂, shedding a new light on the electronic band structure of this interesting material.
