“…Due to the recent advent of two-dimensional materials (e.g. graphene [201][202][203][204][205][206][207][208], hBN [209][210][211][212][213][214][215][216][217], twisted photonic structures [218][219][220][221][222][223][224][225][226][227]) and metasurfaces [89,[228][229][230][231][232][233][234][235], the boundary is uniquely featured with a surface conductivity, which can be rather complex but provide an extra degree of freedom to regulate the free-electron radiation. Without loss of generality, the boundary with a non-zero surface conductivity is termed as the meta-boundary in Fig.…”

Herein, an optoelectronic device synthesized from a CuFeO2/CuO/Cu nanocomposite was obtained through the direct combustion of Cu foil coated with Fe2O3 nanomaterials. The chemical, morphological, and optical properties of the nanocomposite were examined via different techniques, such as XRD, XPS, TEM, SEM, and UV/Vis spectrophotometer. The optical reflectance demonstrated a great enhancement in the CuFeO2 optical properties compared to CuO nanomaterials. Such enhancements were clearly distinguished through the bandgap values, which varied between 1.35 and 1.38 eV, respectively. The XRD and XPS analyses confirmed the chemical structure of the prepared materials. The produced current density (Jph) was studied in dark and light conditions, thereby confirming the obtained optoelectronic properties. The Jph dependency to monochromatic wavelength was also investigated. The Jph value was equal to 0.033 mA·cm−2 at 390 nm, which decreased to 0.031 mA·cm−2 at 508 nm, and then increased to 0.0315 mA·cm−2 at 636 nm. The light intensity effects were similarly inspected. The Jph values rose when the light intensities were augmented from 25 to 100 mW·cm−2 to reach 0.031 and 0.05 mA·cm−2, respectively. The photoresponsivity (R) and detectivity (D) values were found at 0.33 mA·W−1 and 7.36 × 1010 Jones at 390 nm. The produced values confirm the high light sensitivity of the prepared optoelectronic device in a broad optical region covering UV, Vis, and near IR, with high efficiency. Further works are currently being designed to develop a prototype of such an optoelectronic device so that it can be applied in industry.

“…Since its imaginary part of complex conductivity is positive as it is doped by electrostatic or chemical doping techniques [2][3][4][5], tunable graphene surface plasmons (GSPs) are supported on graphene structures in the mid-infrared/THz frequency range [6]. Due to its strong field confinement and unique tunability, GSPs have attracted tremendous investigation and found various novel optical applications, including efficient mid-infrared/THz sources [7][8], modulators [9][10], broadband polarizer [11], plasmonic components [12][13], and optoelectronic components, such as photodetectors [14], etc.…”

In this work, the directional excitation of acoustic graphene plasmons (AGPs) are numerically studied using Finite Element Methods. In our proposed hybrid graphene-metal structure under oblique incidences, not only are AGPs excited efficiently, but also they are unidirectional propagating along a graphene monolayer. Although the symmetry AGPs dispersion relations are broken by oblique incidence, both left and right moved AGPs are excited simultaneously at a resonant wavelength due to almost equaled wavenumbers of directional propagated AGPs. Based on the fact that great AGPs excitation efficiency can’t guarantee high EM energy propagating in one direction, we will focus on how the directional propagating net energy are affected by geometrical parameters. Due to the tunable graphene conductivity, AGPs propagation with great unidirectional net energy can be dynamically controlled by a relatively low externally applied bias voltage (electrostatic gating). The prototype structure may find applications in ultra-confined plasmons launchers and switchers in integrated optics.
