    On the rotational alignment of graphene domains grown on Ge(110) andGe(111)

    We have used low-energy electron diffraction and microscopy to compare the growth of graphene on hydrogen-free Ge(111) and Ge(110) from an atomic carbon flux. Growth on Ge(110) leads to significantly better ro...

    Graphene growth on metal surfaces

    The exceptional properties of graphene originate from its two-dimensional polymeric structure of sp2-bonded carbon. This feature also causes graphene to grow on metal substrates through mechanisms that are striki...

    Vacancies in solids and the stability of surface morphology

    Determining how thermal vacancies are created and destroyed in solids is crucial for understanding many of their physical properties, such as solid-state diffusion. Surfaces are known to be good sources and si...

    Dynamics of the silicon (111) surface phase transition

    The manner in which phase transformations occur in solids determines important structural and physical properties of many materials. The main problem in characterizing the kinetic processes that occur during p...

    Identifying the forces responsible for self-organization of nanostructures at crystal surfaces

    The spontaneous formation of organized surface structures at nanometre scales1,2 has the potential to augment or surpass standard materials patterning technologies. Many observations of self-organization of nanos...

    Million-Line Failure Distributions for Narrow Interconnects

    We examine the distribution of failure times in a simple and computationally efficient, yet reasonably authentic, model of interconnect reliability that allows consideration of statistically significant sample...

    Si(001) Homoepitaxial Growth

    Epitaxial growth is generally treated ns a far-from-equilibrium process, dominated by kinetic restraints rather than thermodynamic driving forces. In this paper we show that homocpitaxial growth, at temperatur...

    Brownian Motion and Coarsening of Domain Boundaries on (7×7)-Si(111)

    We have used low-energy electron microscopy to investigate the real-time motion of (7×7) out-of-phase domain boundaries in the (7×7) reconstruction on vicinal Si(111), just below the phase transition temperatu...

    A Dynamic View of Step Configurations on Ag(110) and Their Role in the Formation of Oxygen Overlayers

    Step fluctuations on Ag(110) surfaces have been investigated with STMT atomic events that underlie these thermal fluctuations are quantified using a Langevin analysis. From the t1- scaling of the step-position co...

    The Role of Surface Stress in the Faceting of Stepped Si(111) Surfaces

    The nucleation and growth of facets on stepped Si(111) have been observed in real time using the newly developed technique of low-energy electron microscopy (LEEM). The results show that the growth of an isola...

    Critical Phenomena of Surface Phase Transitions: Theoretical Studies of the Structure Factor

    Great progress has been made in the theory of the critical properties of phase transitions of lattice gases in two dimensions, but nature has provided very few realizations. Systems of chemisorbed atoms may we...

    Wavevector scaling, surface critical behavior, and wetting in the 2-d, 3-state chiral clock model

    The controversial 2-d, 3-state chiral Potts model is studied using transfer matrix finite size scaling. at Δ=0, we find dq N/dΔ∝N −4/5, whereq is the “wavevector”, Δ the chiral field, andN the strip width (N=4−10...

    Measurement of the Specific Heat Critical Exponent Using LEED

    Near a second-order phase boundary, integrated intensities of “extra” LEED beams exhibit a |T -Tc|1-α singularity, where α is the specific heat critical exponent. We discuss the origin of this effect, apply it to...
