Persistence of charge ordering instability to Coulomb engineering in the excitonic insulator candidate TiSe $_{2}$

Sebastian Buchberger, Yann in 't Veld, Akhil Rajan +11

TiSe $_{2}$ has long been considered one of the best candidate materials to host the elusive excitonic insulator (EI) phase. However, a finite coupling to the lattice can generically…

Electronic structure of monolayer-CrTe $_{2}$ : an antiferromagnetic 2D van der Waals material

Olivia Armitage, Naina Kushwaha, Akhil Rajan +7

Magnetic van der Waals materials are an important building block to realize spintronic functionalities in heterostructures of two-dimensional (2D) materials. Yet, establishing thei…

From ferromagnetic semiconductor to anti-ferromagnetic metal in epitaxial Cr $_{x}$ Te $_{y}$ monolayers

Naina Kushwaha, Olivia Armitage, Brendan Edwards +6

Chromium ditelluride, CrTe $_{2}$ , is an attractive candidate van der Waals material for hosting 2D magnetism. However, how the room-temperature ferromagnetism of the bulk evolves as…
