Simulated STM images for boron sheets on Ag(111). Buckled triangular borophene on Ag(111) at a 0.8, e 0.2, i − 0.4, and m − 1.0 V. β₁₂ borophene on Ag(111) at b 0.8, f 0.2, j − 0.4, and n − 1.0 V. χ₃ borophene on Ag(111) at c 0.8, g 0.2, k − 0.4, and o − 1.0 V. χ₃’ borophene on Ag(111) at d 0.8, h 0.2, l − 0.4, and p − 1.0 V. The green balls represent the boron atoms. The rectangles and rhombus enclosed by solid red lines denote the unit cells of as-grown boron sheets on Ag(111) surface
