Dyakonov Waves in Biaxial Anisotropic Crystals
, 2017 We present the general analytical theory for Dyakonov surface waves at the interface of a biaxial anisotropic dielectric with an isotropic medium. We demonstrate that these surface waves can be divided into todo distinct classes, with qualitatively ...

Optimizing Phononic Crystal Waveguides for Enhanced Surface Acoustic Wave Confinement
physica status solidi (b), Volume 262, Issue 7, July 2025.A phononic crystal consisting of periodic arrays of nanofabricated holes on a surface can form a metamaterial‐like layer with properties different from the host material. Exploiting these surface properties, an optimized waveguide geometry is designed for surface acoustic waves using twofold elliptical cylinder inclusions to create a slow region that ...

Effect of Crystal Symmetry of Lead Halide Perovskites on the Optical Orientation of Excitons
Advanced Science, Volume 12, Issue 15, April 17, 2025.Lead halide perovskite semiconductors provide a platform for studying crystal symmetry effects on spin‐dependent properties via optical orientation of exciton and carrier spins. This study examines exciton spin polarization at 1.6 K in nearly cubic and orthorhombic perovskites.

Nonreciprocal Dyakonov-wave propagation supported by topological insulators [PDF]
, 2016 The propagation of Dyakonov waves guided by the planar interface of a columnar thin film and a topological insulator was investigated by numerically solving the associated canonical boundary-value problem.

Enhanced Cherenkov radiation in twisted hyperbolic Van der Waals crystals
InfoScience, Volume 2, Issue 1, March 2025.Efficient Cherenkov radiation over a wide range of momenta is highly demanded for many applications but still remains a challenging task. Here, we demonstrated that twisted hyperbolic Van der Waals crystals enable enhancement of Cherenkov radiation in a broad range of wave vectors.

Ultralong‐Term High‐Density Data Storage with Atomic Defects in SiC
Advanced Functional Materials, Volume 34, Issue 27, July 3, 2024.A concept of ultralong, high‐density data archiving based on optically active atomic‐size defects in silicon carbide (SiC) is proposed. The information is written in these defects by focused ion beams and read using photoluminescence or cathodoluminescence. The temperature‐dependent deactivation of these defects suggests a retention time minimum over a

Nonlocal dispersion anomalies of Dyakonov-like surface waves at hyperbolic media interfaces
, 2016 Dyakonov-like surface waves (DSWs) propagating obliquely on an anisotropic nanostructure have been theoretically proved in a few cases including 2D photonic crystals and metal-insulator (MI) layered metamaterials.
