Erratum to: Enhanced piezoelectric properties of off-stoichiometric strontium bismuth tantalate Sr0.8Bi2.2Ta2O9 ceramics

The above article was published with the errors in the piezoelectric constants (d33, d31, d15) of S0.8B2.2T ceramics in main text of p. 133 and Table 3 of p. 134. The article showed that the d33, d31, and d15 values are 10.8, 5.2, and 6.0 pC/Nin themain text and 6.0, 13.0, 10.2 pC/N in Table 3, respectively. The correct piezoelectric constants are d33 = 13.0, d31 = 6.0, and d15 = 10.2 pC/N, respectively. The readers can obtain these values by the relevant equations [1] using the electromechanical coupling factors in Table 2 and dielectric, elastic constants in Table 3. The authors regret this oversight.
