a Bi2(Te1-xSex)3 and b (Bi1-ySby)2Te3 bulk crystals in the three-point bending test. HAADF-STEM images (I), IFFT images projected on (003) plane (II), and strain maps (III) of c Bi2(Te0.3Se0.7)3 crystal and d (Bi0.7Sb0.3)2Te3 crystal. The red, yellow, and blue symbols represent ripplocation, swapped-bilayer, and dislocation, respectively.
