(a) Crystal structure of BP from side view. (b) Schematic Brillouin Zone of BP. (c) Large-scale STM topography image of BP surface with scan size 15 nm × 15 nm. (d) Closed-up image of the region corresponding of the selected area in c showing detailed features of the BP surface structure along a- and c- axes. Images were taken with sample-bias voltage of 1.0 V and a tunneling current of 0.15 nA at 77 K.
