High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Investigation on surface plasmon polaritons and localized surface plasmon production mechanism in micro-nano structures

open access: yesJournal of Electronic Science and Technology, 2022
The simulation mechanism of surface plasmon polaritons (SPPs) and localized surface plasmon (LSP) in different structures was studied, including the Au reflection grating (Au grating), Au substrate with dielectric ribbons grating (Au substrate grating ...

Exciton-surface plasmon polariton interactions

open access: yesAdvances in Physics: X, 2020
Exciton-surface plasmon polariton (exciton-SPP) interactions in semiconductor-metal hybrid nanostructures connect two fundamentally different quantum mechanical excitations with strikingly different dispersion relations and optical response.

Surface and Bulk Plasmon Excitation on Aluminum Surface at Small to High Grazing Angles

open access: yesAtoms, 2022
We present a series of spectra measured by reflected electron energy loss spectroscopy on an aluminum sample using a cylindrical mirror analyzer. The measurements were performed in the energy range between 250 eV and 2000 eV and with various incident ...

Surface plasmon polaritons in topological Weyl semimetals [PDF]

open access: yes, 2016
We consider theoretically surface plasmon polaritons in Weyl semimetals. These materials contain pairs of band touching points - Weyl nodes - with a chiral topological charge, which induces an optical anisotropy and anomalous transport through the chiral

Excitonic Emission Modulation in GaSe/MoS2 Van Der Waals Heterostructure Via Plasmonic Control of Interlayer Charge Transfer

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic hybridization enables control of light emission in 2D van der Waals heterojunctions. By stacking multilayer GaSe and monolayer MoS2 on a silver film, light emission is enhanced at the edges due to plasmonic effects. In the center, where these effects are absent, charge transfer led to reduced light emission.

Complex Oxide‐metal Hybrid Metamaterials with Integrated Magnetic and Plasmonic Non‐noble Metal Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A new alloy‐oxide vertically aligned nanocomposite (VAN) thin film with two immiscible non‐noble metal elements of Co and Cu embedded in BaTiO3 (BTO) matrix is designed and fabricated, which presents interesting magnetic, ferroelectric, and optical properties.

Absence of unidirectionally propagating surface plasmon-polaritons at nonreciprocal metal-dielectric interfaces

open access: yesNature Communications, 2020
The local Drude model predicts that, under certain conditions, surface plasmon polaritons at a metal-dielectric surface have a frequency range where only unidirectional propagation is supported.
