The Si(111)5×2-Au surface comprises a quasi-one-dimensional surface reconstruction consisting of Au stripes mediated by honeycomb Si chains. In the present study, using STM observations we explored adsorption of thallium (Tl) onto Si(111)5×2-Au surface as well as growth of C60 layers on Tl-modified and intact Si(111)5×2-Au surfaces. Analysis of the results was based on the recently proposed KK model of Si(111)5×2-Au surface [Kwon and Kang, PRL 113 (2014) 086101]. It was found that intact Si(111)5×2-Au surface produces a poor template effect on the overgrown C60 layers which have a close-packed-like structure without distinct ordering. In contrast, the C60 layers grown on the Tl-adsorbed Si(111)5×2-Au surface where Tl atoms occupy various adsorption sites on the honeycomb Si chains have a well-ordered quasi-one-dimensional structure consisting of straight C60 chains. Ordering of the C 60 molecules is a result of an intricate interplay between adsorbed C60 molecules with each other and with a substrate surface. Separation between neighboring C60 chains is dictated by the periodicity of the underlying Si(111)5 × 2-Au template, while the C60-C60 spacing within the chains of ∼12 Å that is ∼3.2a0 reflects the peculiarity of the C60-C60 intermolecular interaction on the Tl-adsorbed Si(111)5×2-Au surface. Structural information on (Au, Tl)/Si(111) and C 60 /(Au, Tl)/Si(111) systems gained in the present study can be useful for the prospective works on elucidating the ways to control electronic properties of the Si(111)5×2-Au surface using atomic and molecular adsorbates.

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...

Detailed analysis of scanning probe microscopy (SPM) data acquired for faceted and non-flat surfaces is usually complicated due to the presence of a large number of surface areas tilted by large/variable angles relative to the scanning plane. As a consequence, standard methods of elimination of global or local slopes by either a plane subtraction or ...

Massey Products in the Cohomology of the Moment-Angle Manifolds Corresponding to Pogorelov Polytopes

Nontrivial Massey products in the cohomology of the moment-angle manifolds corresponding to polytopes in the Pogorelov class are constructed. This class includes the dodecahedron and all fullerenes, i.e., simple 3-polytopes with only 5- and 6-gonal faces. The existence of nontrivial Massey products implies that the spaces under consideration are not formal in the sense of ...
