a Kelvin Probe Force Microscopy on a pristine major (10-1) face, and b freshly fractured complementary (010/0-10) faces. The arrows indicate the direction of the scan (frame up) during potential mapping. c Topography and potential mapping across a crack line on (10-1). d Time-dependent decay of surface potential on a freshly fractured face perpendicular to the needle axis. Source data are provided as a Source Data file.
