Strain-Correlated Piezoelectricity in Quasi-Two-Dimensional Zinc Oxide Nanosheets.

ABSTRACT: Two-dimensional (2D) piezoelectric materials have recently drawn intense interest in studying the nanoscale electromechanical coupling phenomenon and device development. A critical knowledge gap exists to correlate the nanoscale piezoelectric property with the static strains often found in 2D materials. Here, we present a study of the out-of-plane piezoelectric property of nanometer-thick 2D ZnO-nanosheets (NS) in correlation to in-plane strains, using in situ via strain-correlated piezoresponse force microscopy (PFM). We show that the strain configuration (either tensile or compressive) can dramatically influence the measured piezoelectric coefficient (d₃₃) of 2D ZnO-NS. A comparison of the out-of-plane piezoresponse is made for in-plane tensile and compres
