Synthesis of millimeter-sized MoxW(1−x) S2ySe2(1−y)monolayer alloys with adjustable optical and electrical properties and their magnetic doping

Based on a new liquid phase edge epitaxy (LPEE) method, we have grown millimeter-sized quaternary Mo x W (1− x ) S 2 y Se 2(1− y ) monolayer films and M-doped Mo x W (1− x ) S 2 y Se 2(1− y ) monolayers (M: Fe, Co, and Ni).
