“…At still lower photon energies in the far infrared, 1 becomes negative due to the contribution of free charge carriers thus making possible plasmonic properties. Such properties have been recently explored in Bi microstructures for applications in infrared sensing [26][27].…”

Plasmonic and Mie resonances in subwavelength nanostructures provide an efficient way to manipulate light below the diffraction limit that has fostered the growth of plasmonics and nanophotonics. Plasmonic resonances have been mainly related with the excitation of free charge carriers, initially in metals, and Mie resonances have been identified in Si nanostructures. Remarkably, although much less studied, semi-metals, semiconductors and topological insulators of the p-block enable plasmonic resonances without free charge carriers and Mie resonances with enhanced properties compared with Si. In this review, we explain how interband transitions in these materials show a major role in this duality. We evaluate the plasmonic and Mie performance of nanostructures made of relevant p-block elements and compounds, especially Bi, and discuss their promising potential for applications ranging from switchable plasmonics and nanophotonics to energy conversion, especially photocatalysis.

“…Using only available published L d and L x spectra based on measured permittivity values, we find the following useful spectral ranges, in order of increasing wavelength: Ag (< 2.3 μm) [35], silicides (1-7 μm) [7], PtGe 2 (2-7 μm) [36], Pt 2 Ge 3 (2-15 μm) [36], Si with p = 10 20 cm −3 (6-10 μm) [8], and Sb [11-20 μm] [4]. The semimetal Bi does not satisfy the confinement criterion L d < 3λ at any wavelength from near to far IR [5]. For Si with p = 6 x 10 19 cm −3 , there is no wavelength where both confinement and propagation criteria are satisfied simultaneously [8].…”

“…Many studies of SPPs have been conducted for propagating plasmons on the surface of good metals in the visible spectrum [1,2]. Some studies have been published about IR SPPs on metals [3], semimetals [4,5], dopedsemiconductors [6][7][8][9], and other materials [10][11][12][13][14][15][16][17][18][19][20][21][22].…”

Fluorine-doped tin oxides (FTO) were investigated for infrared plasmonic applications. Nano-crystalline FTO thin films were grown by the SPEED chemical-spray deposition method. Complex permittivity spectra were measured from 1.6 to 12 μm wavelength. These spectra were used to calculate materials parameters, which compared well with values from transport measurements, and to predict characteristics of surface plasmon polaritons (SPP). Reflectivity spectra for lamellar FTO gratings revealed SPP coupling resonances in good agreement with predictions. The FTO film studied here is well suited for plasmonic applications in the important 3-5 μm wavelength range.

“…In this context, resonances were predicted and observed in the long-wave IR on Bi microgratings fabricated by evaporation of Bi on photoresist ridges designed by photolithography. e resonances were attributed to plasmonic modes [114,115]. Far-IR resonances were also predicted theoretically in superlattices made of Bi layers and polaritonic materials [116], which could be fabricated by physical deposition techniques.…”

Along the twentieth century, the electronic properties of bismuth have been widely studied, especially in relation with its magnetoresistive and thermoelectric responses. In this context, a particular emphasis has been made on electronic confinement effects in bismuth nanostructures (or nanobismuth). In the recent years, the optical properties of bismuth nanostructures are focusing a growing interest. An increasing number of reports point at the potential of such nanostructures to support plentiful optical resonances over an ultrabroad spectral range: "interband plasmonic" resonances in the ultraviolet, visible, and nearinfrared; dielectric Mie resonances in mid-and far-infrared; and conventional free-carrier plasmonic resonances in the farinfrared and terahertz. With the aim to provide a comprehensive basis for exploiting the full optical potential of bismuth nanostructures, we review the current progress in their controlled fabrication, the trends reported (from theoretical calculations and experimental observations) for their optical and plasmonic response, and their emerging applications, including photocatalysis and switchable metamaterials.
