Pentagonal tiling with buckybowls: pentamethylcorannulene on Cu(111)


Zoppi, Laura; Bauert, Tobias; Siegel, Jay S; Baldridge, Kim K; Ernst, K-H (2012). Pentagonal tiling with buckybowls: pentamethylcorannulene on Cu(111). Physical Chemistry Chemical Physics (PCCP), 14(38):13365-13369.

Abstract

We present scanning tunnelling microscopy studies and first principles calculation on the 2D crystallization of pentagonal pentamethylcorannulene on a Cu(111) surface under ultrahigh vacuum in the temperature range of 50 K to 400 K. The observed 2D crystal phases and their packing densities are compared to tiling options of hard pentagons. Temperature change-induced reversible phase transitions reveal entropic effects in 2D crystallization. Only inclusion of dispersion interactions into density functional theory yields structures observed experimentally at low temperatures.
