“…dielectric Bragg mirror), here referred to as Bragg TPMs, have been considered previously 8–10 . The fact that such Tamm plasmons appear within the dielectric light cones in both s- and p-polarization, inside the band gap of the Bragg mirror, makes them interesting for applications in lasers 11 , photodetectors 12 , engineering of spontaneous optical emission 10 and chemical and biological refractometric sensors 13,14 .…”

We analyze the fundamental properties of optical waves referred to as Tamm plasmon modes (TPMs) which are tied to the interface of a semi-infinite two-phase metallodielectric superlattice with an arbitrary homogeneous capping medium. Such modes offer new ways of achieving high electromagnetic field localization and spontaneous emission enhancement in the vicinity of the interface in conjunction with absorption loss management, which is crucial for future applications. The homointerface, formed when the capping medium has the same permittivity as one of the superlattice constituents, is found to support a TPM whose dispersion overlaps the single-interface surface plasmon polariton (SPP) dispersion but which has a cut off at the topological transition point. In contrast, a heterointerface formed for an arbitrary capping medium, is found to support multiple TPMs whose origin can be traced by considering the interaction between a single-interface SPP and the homointerface TPM burried under the top layer of the superlattice. By carrying out a systematic comparison between TPMs and single-interface SPPs, we find that the deviations are most pronounced in the vicinity of the transition frequency for superlattices in which dielectric layers are thicker than metallic ones.

“…After scattering with the phonons, they will become the heat dissipation known as Ohmic loss. In fact, hot electrons exist in bulk metals as well as in metal nanostructures . They were well studied in the IPE of Schottky‐junction photodetectors, which, however, exhibits a low efficiency of 0.3–9% .…”

to these characteristics, LD photodetectors based on atomically thin 2D materials (e.g., graphene, MoS 2 , WS 2 , etc.), [3][4][5][6][7] 1D semiconductor nanowires (e.g., ZnO, Si, GaN, SnO 2 , etc.), [8] and 0D QDs (such as the PbS QD layer, the HgTe QD layer, and the InAs QDs in quantum wells) [9][10][11][12] are at the forefront of photodetector research for their competitive device performance in terms of higher responsivity, high photoconductive gain, and fast response speed. While the downscaling of devices hastens the electrical signal due to the short length of the electron transport, the small volume of the LD photodetectors also suffers from low absorption of light, e.g., 2.3% for single-layer graphene. [13] Surface plasmon polariton (SPP) is light-excited collective oscillation of free electrons on an interface between a metal layer and a dielectric medium such as air. [14] Under the SPP mode, the electromagnetic energy of light excitation is converted to the energy of an electromagnetic wave on the interface that exhibits characteristics of both the photons and the electrons. Therefore, the SPP mode can confine incident light on the surface of the metal layer below the diffraction limit, and propagate along the surface. Owing to the confinement, the SPP electromagnetic field could be enhanced by up to 10 5 . [15] This provides a promising solution to the dilemma of LD photodetectors and therefore are widely used in thin-film plasmonic optoelectronic devices. [16] However, excitation of SPPs on the metal layers is conditional and normally entails a special excitation setup, such as gold film-coated prism, to meet momentum conservation requirements, and therefore its use in LD photodetectors is limited. In contrast, localized surface plasmons (LSPs) can be excited by direct illumination on metal nanostructures, such as metal nanoparticles (NPs). Compared to SPP, LSP is confined on the NP surface without propagation, and its enhancement depends on NP size and geometry. [17] Thus, well-developed fabrication methods of metal nanostructures have rendered LSPs a dominant technology for boosting the device performance of LD photodetectors in recent years. [18] As the photodetector materials change from bulk or thin film to the LD ones, plasmonic materials also evolve for optimized enhancement depending on the dimensions of the photo detectors of interests. Silver nanowires are deposited on a 2D MoS 2 as an SPP photodetector. [2] Gold NPs are deposited on 1D nanowire as an LSP-enhanced photodetector. [19] Perforated nanohole arrays are made on a gold film to directly excite Plasmonic nanostructures can achieve subdiffraction-limit light confinement with enhanced electric fields. By taking advantage of the light-confinement effect, various plasmonic photodetectors that combine low-dimensional (LD) semiconductor structures and plasmonic materials have recently demonstrated excellent plasmon-enhanced device performance and attracted significant research interest. In this review, the state-of-the-art progress in...

“…Strong electromagnetic resonance can greatly enhance the absorption of photons by electrons and benefit hot-electron photodetection [32]. A great number of hot-electron photodetections and devices have been realized in various plasmonic nanostructures and metamaterials, which efficiently convert photon into electron [33][34][35][36][37][38][39][40][41][42][43][44]. Hot-electron photodetection can be tuned in graphene-silicon Schottky junctions where the junction bias can modulate the Schottky junction [45][46][47].…”

We report a new type of coherent perfect absorption that is determined by the phase coupling between metaatoms and is referred to as the phase-coupled simultaneous coherent perfect absorption (PC-SCPA) for antisymmetric and symmetric incidences and especially the PC-SCPA for antisymmetric and symmetric incidences can be simultaneously achieved in the same bi-layered Schottky junction metamaterial possessing the phase coupling. Our proposed mechanism exploits the phase coupling between metaatoms, which is in contrast with the existing mechanism which depends on the near-field coupling. The theory of PC-SCPA is provided using coupled mode theory with the phase coupling. The operating wavelengths of PC-SCPA are insensitive to the variations of the spacing distances between metaatoms in the lateral and vertical directions. An infrared PC-SCPA-based hot-electron photodetection with dynamically switchable operating wavelengths and dynamically tunable bandwidth is theoretically and numerically verified in the same bi-layered Schottky junction metamaterial. The peak of spectrum of responsivity for antisymmetric and symmetric incidences can be switched to the same wavelength only by altering the phase coupling. Our study may build the bridge among the new type of PC-SCPA, metamaterial, and hot electron and may find potential and significant applications in hot-electron photodetection.
