摘要
Nanoindentation rosettes have been observed by scanning Kelvin probe microscopy on chemomechanical polished and etched {0001}ZnO while under illumination by a broadband light source. The rosette pattern consisted of a central region with a lower surface potential extending beyond the indentation and six arms emanating from this region along the < 11 (2) over bar0 > directions. The length of the longest rosette arm was found to be proportional to the square root of the maximum force of indentation minus the average load at which pop-in occurred.
