With the continuous scientific advancement, electronic devices need to be with low power, lightweight, and multi-functionality. To achieve these goals, develop a novel material candidate will be a key approach. Transition metal dichalcogenide (TMDC), owing to its scalabiity, structural tunability, and flexibility, has received great attentions. Moreover, hetero-structure from two different material combinations is another advantage of TMDC enabling a more promising future for commercial electronics to be expected.
