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…
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…
Two-Dimensional Itinerant Ising Ferromagnetism in Atomically thin Fe3GeTe2
Zaiyao Fei, Bevin Huang, Paul Malinowski +11
Recent discoveries of intrinsic two-dimensional (2D) ferromagnetism in insulating/semiconducting van der Waals (vdW) crystals open up new possibilities for studying fundamental 2D…
