Singular existence of a Dyakonov–Voigt surface wave: Proof
Results in Physics, 2021 If Dyakonov surface-wave (DSW) propagation can be guided by the planar interface of an isotropic dielectric medium and a uniaxial dielectric medium with its optic axis lying wholly in the interface plane, then a Dyakonov–Voigt surface wave can propagate in at most one direction within the angular sector for DSW propagation.

Temperature-mediated transition from Dyakonov–Tamm surface waves to surface-plasmon-polariton waves [PDF]
Journal of Optics, 2017 The effect of changing the temperature on the propagation of electromagnetic surface waves (ESWs), guided by the planar interface of a homogeneous isotropic temperature-sensitive material (namely, InSb) and a temperature-insensitive structurally chiral material (SCM) was numerically investigated in the terahertz frequency regime.

Steering visible Dyakonov surface waves at the hyperbolic metasurface
, 2021 Dyakonov surface wave existing at the interface with anisotropy offers a promising way of guiding light in two-dimension with almost no loss. However, predicted decades ago, the experimental demonstration of the Dyakonov surface wave seems always challenging for the weak anisotropic indices from the natural materials.

Controllable selective coupling of Dyakonov surface wave at liquid-crystal-based interface [PDF]
Conference on Lasers and Electro-Optics, 2020 A selective coupling behavior of Dyakonov surface wave at the liquid-crystal-based interface has been demonstrated experimentally. Such a highly directional and lossless surface wave has promising applications in two-dimensional photonic circuits and devices.

Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes
Advanced Materials, Volume 38, Issue 23, 22 April 2026.Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

On Dyakonov–Voigt surface waves guided by the planar interface of dissipative materials [PDF]
Journal of the Optical Society of America B, 2019 Dyakonov-Voigt (DV) surface waves guided by the planar interface of (i) material $A$ which is a uniaxial dielectric material specified by a relative permittivity dyadic with eigenvalues $ε^s_A$ and $ε^t_A$, and (ii) material $B$ which is an isotropic dielectric material with relative permittivity $ε_B$, were numerically investigated by solving the ...

Resonant Dyakonov–Shur Magnetoplasmons in Graphene Terahertz Photodetectors
Nanophotonics, Volume 15, Issue 8, 24 April 2026.Cavity‐confined Dyakonov–Shur plasmons in graphene evolve into magnetoplasmons by an external perpendicular magnetic field. Gate‐tunable THz photocurrent spectroscopy reveals their dispersion over a broad frequency range, uncovering a nonmonotonic behavior in monolayer graphene in contrast to the conventional response of bilayer graphene.

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals
Advanced Functional Materials, Volume 36, Issue 18, 2 March 2026.Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.
