“…These methods include liquid exfoliation [8,9], hydrothermal synthesis [10,11], pyrolysis [12], chemical vapor deposition [13] and electrochemical Li-intercalation [14]. TMDCs have a wide variety of mechanical and electronic applications with semiconductors of MoS 2 [15,16], MoSe 2 [17,18], WS 2 [19,20] and WSe 2 [21,22]. In particular, the WS 2 material consists of 2D covalently bonded S-W-S layers separated by a van der Waals gap.…”
