Magnetization and Josephson current coupling drives the Josephson diode effect in FeTe0.55Se0.45 van der Waals junctions
Seung-Hyun Shin, Cheong-Eung Ahn, Chang-Won Choi +5
The Josephson diode effect (JDE) reflects symmetry breaking in the current-phase relation (CPR) of Josephson junctions, yet establishing its microscopic origin is often challenging…
Pre-Patterned Superconducting Contacts for Clean Superconductor-Topological Material Interfaces Enabling Long-Range Josephson Coupling
Yong-Bin Choi, Chang-Won Choi, Luke Holtzman +8
Phase-coherent superconducting proximity in topological materials requires clean superconductor-topological material (SC-TM) interfaces, yet conventional top-contact fabrication of…
Thermodynamically driven tilt grain boundaries of monolayer crystals using catalytic liquid alloys
Min-Yeong Choi, Chang-Won Choi, Dong-Yeong Kim +4
We report a method to precisely control the atomic defects at grain boundaries (GBs) of monolayer MoS2 by vapor-liquid-solid (VLS) growth using sodium molybdate liquid alloys, whic…
Interstitially bridged van der Waals interface enabling stacking-fault-free, layer-by-layer epitaxy
GunWoo Yoo, TaeJoon Mo, Yong-Sung Kim +10
Van der Waals (vdW) crystals are prone to twisting, sliding, and buckling due to inherently weak interlayer interactions. While thickness-controlled vdW structures have attracted c…
