Annihilation of point defects on a line

Physical Review E, 2002
We discuss the evolution of the distribution function of distances between point defects of opposite signs distributed on a line of finite length interacting via a potential attractive at short distances and repulsive at large distances. The standard deviation of the distribution grows quickly at short times, attains maximum, and decreases ...

Line Defects and the Glass Transition

Annals of the New York Academy of Sciences, 1981
The structure of glasses contains line defects, characterized by oddness rather than intensity. The density of these defects in equilibrium, above a given temperature T0 where they are free to move, is proportional to the fluidity of the supercooled liquid and follows a simple function of the temperature known empirically as the VOGEL-FULCHER law.

RKKY interaction in graphene with a line defect

Journal of Physics: Condensed Matter, 2015
A kind of extended line defect is currently an experimentally available one-dimensional topological structure in graphene lattice. It modifies the electronic properties of graphene in many aspects. For example, it induces an even-parity boundary state which has linear dispersion and breaks the electron-hole symmetry of the graphene electronic structure.

Walk of a Line Defect in Quasicrystals

Meccanica, 2005
Quasicrystalline alloys are quasiperiodic aggregates in which local atomic changes (phason activity) influence prominently the gross deformative behavior. The effects of these rearrangements on a line defect are analyzed here. Balances of standard and phason interactions are derived along the line together with the balance of actions driving eventually

On Guided Waves Created by Line Defects

Journal of Statistical Physics, 2008
Guided waves in photonic crystal fibers are studied. Here a photonic crystal is treated as though it is a perfect two-dimensional photonic crystal with a line defect in the axial direction. By assuming that the background spectrum has gaps, a simple condition is found on the parameters of the medium and on the line defect, that ensures the rise of the ...

Charge Transport in Borophene: Role of Intrinsic Line Defects

Journal of Physical Chemistry C, 2019
Very recently, the borophene line defects assembled with υ1/6 and υ1/5 rows were experimentally observed. As the lightest 2D metal sheet, borophene may realize applications in transparent electronic interconnects and electrodes.

Carbon Nanotubes with an Extended Line Defect

Small, 2008
Using concepts of defects in graphene lattices (see image) a new class of semiconducting carbon nanotubes is predicted, with an unusual one-dimensional electronic structure. These CNTs are of comparable stability to known carbon nanostructures, have similar mechanical properties, and may be useful in applications based on a combination of electronic ...

Helical edge states of topological photonic crystals with line defects.

Applied Optics, 2019
Topologically protected edge states of honeycomb photonic crystals (PCs) have been extensively studied in recent years. Here we propose several optimized two-dimensional PC configurations with distinct line defects introduced by breaking the C6 symmetry ...
