model reveals R-factors below 0.1 for both, Si 2p and Pt 4f signals. The unit cell of the structural arrangement contains 4 platinum atoms with a periodicity of ([3, −6]; [4, 0]). The topmost silicon layer [...] forming a low-dimensional surface alloy. While the sample is held on a temperature of T = 400 °C, 0.2 ML silicon are deposited via physical vapor deposition. The investigation with LEED reveals a combination [...] recorded for Au 4f and Si 2p are simulated with different structural arrangements. R-factors below 0.1 indicate an excellent agreement with the measured data. The resulting structure model is consistent …
