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…
Distance-based measures and Epsilon-measures for measurement-based quantum resources
Arindam Mitra, Sumit Mukherjee, Changhyoup Lee
Quantum resource theories provide a structured and elegant framework for quantifying quantum resources. While state-based resource theories have been extensively studied, their mea…
