Distinct from conventional 2H-MoS2, recently synthesized 3R-MoS2 exhibits a noncentrosymmetric atomic structure of the trigonal “building blocks” and, thus, remarkable piezoelectric characteristics of ultrathin 3R-MoS2 flakes are predicated theoretically. This paper reveals, for the first time, very...
