Temperature–Mediated Transition From Dyakonov Surface Waves to Surface–Plasmon–Polariton Waves

open access: yesIEEE Photonics Journal, 2016
The propagation of electromagnetic surface waves, guided by the planar interface of a temperature-sensitive isotropic material and a temperature-insensitive uniaxial material, each characterized by a relative permittivity dyadic, was investigated ...

Wetting transitions on biomimetic surfaces [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
Biomimetic hierarchical surfaces demonstrate a potential for a variety of green technologies, including energy conversion and conservation, owing to their remarkable water repellence. The design of such surfaces allowing emerging green applications remains a challenging scientific and technological task.

Surface Verwey Transition in Magnetite [PDF]

open access: yesPhysical Review Letters, 2007
We report density functional studies of the (001) surface of magnetite that account for local Coulomb interactions. Iron cations in the surface layers exhibit charge and t2g orbital ordering that is coupled with the lattice strains. Orbital ordering is present for various surface stoichiometries and causes opening of the band gap Eg approximately 0.3 ...

Photodeposited metal-semiconductor nanocomposites and their applications

open access: yesJournal of Materiomics, 2018
While two-dimensional layered nanomaterials including transition metal oxides and transition metal dichalcogenides have been widely researched because of their unique electronic and optical properties, they still have some limitations.

Phase transitions in random surfaces

open access: yesNuclear Physics B, 1989
Abstract We investigate the statistical properties of triangulated random surfaces of fixed connectivity embedded in d-dimensional space and weighted with an action that contains the extrinsic curvature of the surface as well as the usual Nambu-Goto term. Numerically, we find no second-order phase transition for finite values of the rigidity coupling,

Wetting transition on heated microstructrured superhydrophobic surface

open access: yesAIP Advances, 2019
Superhydrophobic surface has attracted significant attention since their potentiality to industrial and academic applications. Moreover, superhydrophobic surface wettability at non-ambient temperature, especially at high temperature (but not boiling) was

Metal-Insulator Transitions at Surfaces [PDF]

open access: yes, 2007
Various types of metal-insulator transitions are discussed to find conditions for which an ideal surface of a bulk insulator is metallic. It is argued that for the correlation-driven Mott metal-insulator transition the surface phase diagram should be expected to have the same topology as the phase diagram for magnetic order at surfaces: The ...

Improved Transition Metal Dichalcogenides-Based Surface Plasmon Resonance Biosensors

open access: yesCondensed Matter, 2019
Surface plasmon resonance (SPR) biosensors based on transition metal dichalcogenides (TMDC) materials have shown improved performance in terms of sensitivity, detection accuracy (DA), and quality factor (QF) over conventional biosensors.
