Fig. 1: Atomic structure of phosphorus chains on Ag(111).
From: Probing charge redistribution at the interface of self-assembled cyclo-P5 pentamers on Ag(111)
a STM topographic image after sublimation of phosphorus atoms on Ag(111) leading to P chains (1) and cyclo-P5 domains (2), (It = 1 pA, Vs = 0.15 mV). The inset shows an STM image of the single, double, and triple chains, respectively. b–d Series of AFM images with CO-terminated tip revealing the armchair structure of single, double, and triple P chains, (f0 = 26 kHz, A = 50 pm). Scale bars are 0.5 nm. e Atomic configurations of the triple armchair chains obtained by DFT calculations. Phosphorus and silver atoms are shown in orang and gray, respectively. f Corresponding AFM simulation using the DFT coordinates.
