One-dimensional metal chains on Pt vicinal surfaces
High-density arrays (5310 cm) of parallel nanowires have been grown using the vicinal Pt~997! surface as a template. Single monatomic rows of Ag and Cu can be deposited with subrow precision. We demonstrate real-time monitoring and characterization of the growth of the atomic chains as a function of temperature by thermal energy helium atom scattering. Scanning tunneling microscopy provides fur...
متن کاملPhonons of Metallic Vicinal Surfaces
We present an analysis of the vibrational dynamics of metal vicinal surfaces using the embedded atom method to describe the interaction potential and both a real space Green’s function method and a slab method to calculate the phonons. We report two main general characteristics : a global shift of the surface vibrational density of states resulting from a softening of the force field. The latte...
متن کاملBosonizations, Vicinal Surfaces, and Hydrodynamic Fluctuation Theory
We relate bosonic density uctuations of a Fermi uid in one dimension to surface uctuations. Thereby we easily identify the parameters governing the low energy, Luttinger liquid behavior. In particular we recover the Haldane relation in case the surface is tilted only transversely to the Euclidean time direction. We develop a hydrodynamic uctuation theory for the world lines of particles. Since ...
متن کاملStep Patterns on Vicinal Reconstructed Surfaces
Step patterns on vicinal (2× 1) reconstructed surfaces of noble metals Au(110) and Pt(110), miscut towards the (100) orientation, are investigated. The free energy of the reconstructed surface with a network of crossing opposite steps is calculated in the strong chirality regime when the steps cannot make overhangs. It is explained why the steps are not perpendicular to the direction of the mis...
متن کاملInstability and wavelength selection during step flow growth of metal surfaces vicinal to fcc(001).
We study the onset and development of ledge instabilities during growth of vicinal metal surfaces using kinetic Monte Carlo simulations. We observe the formation of periodic patterns at [110] close packed step edges on surfaces vicinal to fcc(001) under realistic molecular beam epitaxy conditions. The corresponding wavelength and its temperature dependence are studied in detail. Simulations sug...
