Optically driven ultrafast lattice contraction in a topological crystalline insulator
M. H. Berntsen, W. Chen, D. Phuyal +9
The ability to dynamically control topological order remains a central challenge in the exploration of quantum materials. Here, we investigate the lattice and electronic response o…
Extreme Strain Controlled Correlated Metal-Insulator Transition in the Altermagnet CrSb
Cong Li, Mengli Hu, Jianfeng Zhang +14
Correlated flat bands and altermagnetism are two important directions in quantum materials, centred respectively on interaction-dominated phases and symmetry-enforced spin-textured…
Hidden Moiré Topology of Low-Symmetry Weyl Surfaces
Cong Li, Zhilong Yang, Hongxiong Liu +11
Topological materials are defined by the correspondence between bulk topology and boundary states, yet this correspondence becomes enigmatic on low-symmetry surfaces where bulk and…
Ultra-clean interface between high k dielectric and 2D MoS2
Han Yan, Yan Wang, Yang Li +8
Atomically thin transition metal dichalcogenides (TMDs) are promising candidates for next-generation transistor channels due to their superior scaling properties. However, the inte…
Experimentally observed defect tolerance in the electronic structure of lead bromide perovskites
Gabriel J. Man, Aleksandr Kalinko, Dibya Phuyal +3
Point defect tolerance in materials, which extends operational lifetime, is essential for societal sustainability, and the creation of a framework to design such properties is a gr…
In-situ exfoliation method of large-area 2D materials
Antonija Grubišić-Čabo, Matteo Michiardi, Charlotte E. Sanders +6
The success in studying 2D materials inherently relies on producing samples of large area, and high quality enough for the experimental conditions. Because their 2D nature surface…
