Enhanced superconductivity in few-layer TaS due to healing by oxygenation
J. Bekaert, E. Khestanova, D. G. Hopkinson +15
When approaching the atomically thin limit, defects and disorder play an increasingly important role in the properties of two-dimensional materials. Superconductivity is generally…
Atomic reconstruction in twisted bilayers of transition metal dichalcogenides
Astrid Weston, Yichao Zou, Vladimir Enaldiev +17
Van der Waals heterostructures form a massive interdisciplinary research field, fueled by the rich material science opportunities presented by layer assembly of artificial solids w…
Stacking Order in Graphite Films Controlled by Van der Waals Technology
Yaping Yang, Yi-Chao Zou, Colin R. Woods +10
In graphite crystals, layers of graphene reside in three equivalent, but distinct, stacking positions typically referred to as A, B, and C projections. The order in which the layer…
Ultra-thin van der Waals crystals as semiconductor quantum wells
Johanna Zultak, Samuel Magorrian, Maciej Koperski +11
Control over the electronic spectrum at low energy is at the heart of the functioning of modern advanced electronics: high electron mobility transistors, semiconductor and Capasso…
Two-dimensional covalent crystals by chemical conversion of thin van der Waals materials
Vishnu Sreepal, Mehmet Yagmurcukardes, Kalangi S. Vasu +14
Most of the studied two-dimensional (2D) materials have been obtained by exfoliation of van der Waals crystals. Recently, there has been growing interest in fabricating synthetic 2…
Atomically-thin micas as proton conducting membranes
L. Mogg, G. -P. Hao, S. Zhang +6
Monolayers of graphene and hexagonal boron nitride (hBN) are highly permeable to thermal protons. For thicker two-dimensional (2D) materials, proton conductivity diminishes exponen…
Self-limiting growth of two-dimensional palladium between graphene oxide layers
Yang Su, Eric Prestat, Chengyi Hu +9
The ability of different materials to display self-limiting growth has recently attracted enormous attention due to the importance of nanoscale materials in applications for cataly…
Micromagnetometry of two-dimensional ferromagnets
M. Kim, P. Kumaravadivel, J. Birkbeck +14
The study of atomically thin ferromagnetic crystals has led to the discovery of unusual magnetic behaviour and provided insight into the magnetic properties of bulk materials. Howe…
Indirect to direct gap crossover in two-dimensional InSe revealed by ARPES
Matthew Hamer, Johanna Zultak, Anastasia V. Tyurnina +16
Atomically thin films of III-VI post-transition metal chalcogenides (InSe and GaSe) form an interesting class of two-dimensional semiconductor that feature strong variations of the…
