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…
Giant Tunneling Magnetoresistance in Spin-Filter van der Waals Heterostructures
Tiancheng Song, Xinghan Cai, Matisse Wei-Yuan Tu +12
Magnetic multilayer devices that exploit magnetoresistance are the backbone of magnetic sensing and data storage technologies. Here we report novel multiple-spin-filter magnetic tu…
