Piezoelectric and elastic properties of free-standing GaPO4 nanosheet. a AFM topography and b–d vertical piezoresponse of free-standing GaPO4 nanosheet at different AC drive excitation. e AFM image of a free-standing GaPO4 flake with DMT modulus map (inset). f DMT modulus distributions measured for the flat section (area B of e) of the GaPO4 sheet. The Gaussian mean value of the modulus is found around 15.66 ± 0.0095 GPa
