STM images of the SrTiO3(111)-(4 × 4) reconstruction. a Left-handed chiral units image constructed by averaging 297 defect-free tiles (image width 4.2 nm, Vs = 2.0 V, It = 0.5 nA). b Right-handed chiral units image constructed by averaging 15 defect-free tiles (image width 4.2 nm, Vs = 2.0–2.5 V, It = 0.5–0.65 nA). c Large area image where the reconstructed units associated with the left (blue) and right (green) chiralities have been automatically identified and labelled (image width 42 nm, Vs = 2.0 V, It = 0.5 nA)
