Extended Data Fig. 3: Cross-sectional DF-TEM.
a, Image of a (100)pc cross section taken under the g = 020pc excitation condition. b, Image of the same (100)pc cross section taken under the g = 002pc excitation. c, Image of a (010)pc cross section (that is, cut at 90° from a and b) taken using g = 002pc. The scale bars are 20 nm.
