Fig. 2: Atomic structure of the SATO thin film observed along the three characteristic low-index zone axes.
From: Ferroelectric ultraviolet photodetector material with ultrafast response speed
a–c HAADF STEM images along the \([11\bar{2}0]\), \([1\bar{1}00]\), and [0001] zone axes of the SATO thin film, respectively. d–f Corresponding ABF STEM images. The atomic models were attached to each image. The green balls represent Sr atoms. The orange, yellow, pink, and dark green balls represent Al atoms. The blue balls represent Ti or Al atoms occupying the same symmetry position. The red balls represent O atoms. Scale bar, 1 nm.
