Hidden spin-texture at topological domain walls drive exchange bias in a Weyl semimetal
Avia Noah, Filip Toric, Tomer D. Feld +11
Exchange bias is a phenomenon critical to solid-state technologies that require spin valves or non-volatile magnetic memory. The phenomenon is usually studied in the context of mag…
Quantum phase transitions of tri-layer excitons in atomically thin heterostructures
Yevgeny Slobodkin, Yotam Mazuz-Harpaz, Sivan Refaely-Abramson +3
We determine the zero temeperature phase diagram of excitons in the symmetric transition-metal dichalcogenide tri-layer heterosctructure WSe2/MoSe2/WSe2. First principle calculatio…
Tunneling in graphene-topological insulator hybrid devices
Hadar Steinberg, Lucas A. Orona, Valla Fatemi +4
Hybrid graphene-topological insulator (TI) devices were fabricated using a mechanical transfer method and studied via electronic transport. Devices consisting of bilayer graphene (…
