Two Distinct Phonon Wave Effects Control Thermal Transport across the Coherent–Incoherent Regime in Superlattices

open access: yesAdvanced Science, EarlyView.
Thermal transport in smooth‐interface superlattices is studied using the phonon Wigner transport equation, which captures both particle‐like and wave‐like contributions. A minimum in cross‐plane thermal conductivity emerges with increasing period thickness, signaling a crossover from coherent to incoherent phonon transport.

Radio telecommunication systems of the terahertz range

open access: yesElectronics and Communications, 2011
В статье рассматриваются состояние и преимущества использования радиотелекоммуникационных систем терагерцового диапазона (от 100 ГГц до 3000 ГГц), сферы использования таких технологий, проблемы и возможные методы их решения. Частотный ресурс используемого в настоящее время радиодиапазона физически не способен передавать сверх- и высокоскоростные потоки

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser

open access: yesAdvanced Science, EarlyView.
An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling

Large Anomalous Hall Effect, Non‐Vanishing Berry Curvature in (110) FeRh Antiferromagnet Films via Interface Strain

open access: yesAdvanced Science, EarlyView.
This study demonstrates a strain‐tunable anomalous Hall response in the (110)‐oriented FeRh thin film. First‐principles calculations reveal that strain‐induced symmetry lowering redistributes Berry curvature near the Fermi level via band shifts and avoided crossings.

Spoof Zenneck waves in terahertz spectral range

open access: yes, 2020
We theoretically predict existence of Spoof Zenneck waves in the terahertz spectral range that are supported by corrugated surfaces with subwavelength patterning made of materials with high positive dielectric permittivities.

Fluence and polarisation dependence of GaAs based Lateral Photo-Dember terahertz emitters

open access: yes, 2014
We characterise THz output of lateral photo-Dember (LPD) emitters based on semi-insulating (SI), unannealed and annealed low temperature grown (LTG) GaAs.

Semiconducting THO‐C3N Monolayers for Ultrahigh Anisotropic Carrier Mobility

open access: yesAdvanced Science, EarlyView.
A precise site‐specific N‐doping strategy that drives a secondary electronic transition in net W is proposed, enabling the electronic properties transition from metal to Dirac semimetal and ultimately to semiconductor. The obtained THO‐C3N‐2 and THO‐C3N‐3 semiconductors exhibit high carrier mobilities and pronounced mobility anisotropy, with THO‐C3N‐2 ...

Label‐Free and Immobilization‐Free Protein‐Binding Assays by Ultraviolet Transient Absorption Microscopy

open access: yesAdvanced Science, EarlyView.
A femtosecond UV pump–probe microscope resolves binding‐induced changes in protein excited‐state dynamics and converts these intrinsic contrasts into an equilibrium affinity readout. By probing tryptophan responses directly in solution, the approach enables quantitative determination of dissociation constants without labeling or immobilization ...
