Persistence of charge ordering instability to Coulomb engineering in the excitonic insulator candidate TiSe
Sebastian Buchberger, Yann in 't Veld, Akhil Rajan +11
TiSe 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: 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 CrTe monolayers
Naina Kushwaha, Olivia Armitage, Brendan Edwards +6
Chromium ditelluride, CrTe, is an attractive candidate van der Waals material for hosting 2D magnetism. However, how the room-temperature ferromagnetism of the bulk evolves as…
Orbital-selective Band Hybridisation at the Charge Density Wave Transition in Monolayer TiTe
T. Antonelli, W. Rahim, M. D. Watson +12
An anomalous charge density wave (CDW) phase emerges in monolayer 1T-TiTe which is absent for the bulk compound, and whose origin is still poorly understood. Here,…
Tomographic mapping of the hidden dimension in quasi-particle interference
C. A. Marques, M. S. Bahramy, C. Trainer +7
Quasiparticle interference (QPI) imaging is well established to study the low-energy electronic structure in strongly correlated electron materials with unrivalled energy resolutio…
Direct observation of the energy gain underpinning ferromagnetic superexchange in the electronic structure of CrGeTe
Matthew D. Watson, Igor Marković, Federico Mazzola +12
We investigate the temperature-dependent electronic structure of the van der Waals ferromagnet, CrGeTe. Using angle-resolved photoemission spectroscopy, we identify atomic- and…
Morphology Control of Epitaxial Monolayer Transition Metal Dichalcogenides
Akhil Rajan, Kaycee Underwood, Federico Mazzola +1
To advance fundamental understanding, and ultimate application, of transition-metal dichalcogenide (TMD) monolayers, it is essential to develop capabilities for the synthesis of hi…
Proximity-induced ferromagnetism and chemical reactivity in few layers VSe2 heterostructures
G. Vinai, C. Bigi, A. Rajan +11
Among Transition-Metal Dichalcogenides, mono and few-layers thick VSe2 has gained much recent attention following claims of intrinsic room-temperature ferromagnetism in this system…
