WebChemical patterns proposed in 1952 by the British mathematician Alan Turing have been discovered at the atomic scale. Appearing as stripes in a single atomic layer of bismuth adsorbed on crystalline niobium selenide, the patterns are only 2nm (around five atoms) wide – much smaller than all other Turing patterns. WebThey are all man-made and have been synthesised in only fantastically small quantities, by combining the atoms of two lighter elements. They are all highly radioactive, with very short half-lives, severely limiting the practical chemistry that can be performed on them.
WebBismuth films with thicknesses between 6 and ∼30 nm were grown on Si (111) substrate by molecular beam epitaxy (MBE). Two main phases of bismuth — α-Bi and β-Bi — were identified from high-resolution X-ray diffraction (XRD) measurements. The crystal structure dependencies on the layer thicknesses of these films were analyzed. β-Bi layers … WebBismuth is a chemical element with atomic number 83 which means there are 83 protons in its nucleus.
