Figure 1: Analysis of a self-assembled monolayer of fullerenes on 2Pt–Pt3Ti(111).
From: Interface-driven formation of a two-dimensional dodecagonal fullerene quasicrystal
(a) Low-temperature UHV-STM image of a fullerene monolayer deposited on a Pt3Ti(111) single crystal terminated by two layers of Pt (2Pt–Pt3Ti(111)) showing two differently oriented hexagonal (Hex1, Hex2) domains and one QC domain. Within the latter domain, two dodecagons with their inner hexagons rotated by ∼30° are marked. The indicated orientation of the substrate is determined directly from the atomically resolved 2Pt–Pt3Ti(111) surface (scale bar, 5 nm; Uset=−2.03 V, Iset=0.47 nA, 77 K). (b,c) FFT of the STM image and LEED pattern (energy: 19.5 eV), respectively, showing the spots of the two hexagonal domains (red and green circles) and the quasicrystalline domain with 12-fold symmetry (yellow circles).
