The AFAM and ultrasonic piezo-mode techniques described here lend itself for studying materials properties in ceramics on a nanoscale. Whereas the various imaging modes become more and more routine, the application on the AFM and ultrasonic AFM technique to study crack propagation are still in the early stage. However, the results presented here show that these techniques may provide much wanted information on the elastic, piezoelectric, and fracture mechanical behaviour of ceramics during crack propagation.
