The experimental results demonstrate that the structures of MoS<sub>2</sub>/WS<sub>2</sub> heterojunctions can be controlled by adjusting the Mo/S ratio. In addition, lateral heterojunctions exhibit a significantly higher carrier separation efficiency than vertical heterojunctions. Specifically, the interlayer charge transfer time in the lateral heterojunction is approximately 1.2 ps, in contrast to the value of about 4.0 ps in the vertical heterojunction. First-principles simulations reveal that the lateral heterojunction has stronger interface coupling and orbital hybridization, contributing to its faster charge transfer rate.
