Components of the piezoelectric modulus tensor in graphene-like carbon 2D supracrystals with a periodic perforation breaking the centrosymmetry of the structure have been calculated. It has been shown that the piezoelectric moduli of the supracrystals with sp (2) hybridization are one order of magnitude lower and those of the supracrystals with sp (3) hybridization are several time higher than in lithium niobate.
