Classification and identification of TDs observed by the multiphoton excitation photoluminescence method. From the contrast difference of the dark line and the distribution map of the inclination angle from the c-axis (left), it can be seen that the TDs have three types of properties. From the inclination angle and the distribution in the in-plane direction of the inclination (right), the distribution has a six-fold symmetry according to the in-plane symmetry of the Burgers vector of mixed TDs.
