Fig. 6: STM image and molecular model of the 1D-disordered racemates.

a STM image of the 1D-disordered racemic structures was obtained at 1.1 ML. For clarity, the adjacent zigzag rows are painted in different colors. b Molecular model of the 1D-disordered racemic structures. Tunneling conditions: Vbias = −0.5 V, It = 100 pA. Scale bars: a 2 nm. b 1 nm.
