a Side view of the differential electron state distribution perpendicular to the c-axis. Blue and red sections represent positive and negative differential electronic states, respectively, with electron state density displayed using the K-R-W-B-K palette. b–f Cross-sectional views of the absolute electron state distribution along the open-core TSD. Demonstrating the roles of Ga dangling bonds and horizontal and vertical Ga-N dipoles in facilitating electron transport along the dislocation sidewall, with electron state density displayed using the W-R-K-B-W palette. g Top view of the differential electron state distribution at the position of Fig. 5e, illustrating the dipoles distribute around the dislocation core. The palette used in Fig. 5g is consistent with that in Fig. 5a.
