Direct Transformation of Crystalline MoO<sub>3</sub> into Few-Layers MoS<sub>2</sub>

Direct Transformation of Crystalline MoO<sub>3</sub> into Few-Layers MoS<sub>2</sub>

We fabricated large-area atomically thin MoS<sub>2</sub> layers through the direct transformation of crystalline molybdenum trioxide (MoO<sub>3</sub>) by sulfurization at relatively low temperatures. The obtained MoS<sub>2</sub> sheets are polycrystalline (~10–20...
