Gate-induced superconductivity in a monolayer topological insulator
Ebrahim Sajadi, Tauno Palomaki, Zaiyao Fei +7
The layered semimetal WTe_2 has recently been found to be a two-dimensional topological insulator (2D TI) when thinned down to a single monolayer, with conducting helical edge chan…
Ferroelectric switching of a two-dimensional metal
Zaiyao Fei, Wenjin Zhao, Tauno A. Palomaki +6
A ferroelectric is a material with a polar structure whose polarity can be reversed by applying an electric field. In metals, the itinerant electrons tend to screen electrostatic f…
Signatures of moiré-trapped valley excitons in MoSe/WSe heterobilayers
Kyle L. Seyler, Pasqual Rivera, Hongyi Yu +6
The creation of moiré patterns in crystalline solids is a powerful approach to manipulate their electronic properties, which are fundamentally influenced by periodic potential land…
Stacking-Dependent Magnetism in Bilayer CrI
Nikhil Sivadas, Satoshi Okamoto, Xiaodong Xu +2
We report the connection between the stacking order and magnetic properties of bilayer CrI using first-principles calculations. We show that the stacking order defines the magn…
Imaging Quantum Spin Hall Edges in Monolayer WTe2
Yanmeng Shi, Joshua Kahn, Ben Niu +9
A two-dimensional (2D) topological insulator (TI) exhibits the quantum spin Hall (QSH) effect, in which topologically protected spin-polarized conducting channels exist at the samp…
Voltage Control of a van der Waals Spin-Filter Magnetic Tunnel Junction
Tiancheng Song, Matisse Wei-Yuan Tu, Caitlin Carnahan +8
Atomically thin chromium triiodide (CrI3) has recently been identified as a layered antiferromagnetic insulator, in which adjacent ferromagnetic monolayers are antiferromagneticall…
