Lateral piezoelectric response across ferroelectric domain walls in thin films

J. Guyonnet, H. Bea, P. Paruch

In purely c-axis oriented PbZr${}_{0.2}$Ti${}_{0.8}$O${}_3$ ferroelectric thin films, a lateral piezoresponse force microscopy signal is observed at the position of 180°domain walls, whe…
