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…
