“…Surface modification presented by improved surface charges transfer which is achieved by the metal layer coating could also account for the enhanced light absorption [20]. In addition the plasmonic metal nanoparticles and nanostructures light trapping inside the active layer may result in enhanced light absorption [21]. We shall also consider that the ionic radius of Al +3 being 53.5 pm [22] is less than that of W +6 (67 pm [18]).…”

Herein the effects of aluminum nanosheets on the structural, morphological, optical and electrical properties of tungsten oxide thin films are reported. Polycrystalline phase of the thermally evaporated WO3 was achieved by the pulsed laser welding technique. The polycrystalline films are then coated with Al nanosheets of thicknesses of 100 nm and 150 nm by the ion coating technique. It is observed that Al induces the domination of the hexagonal structure of WO3 over the tetragonal. Associated with the enhanced crystallinity the light absorption in the films increased by more than 60 % and the energy band gap narrowed significantly. Namely the energy band gap of the as grown WO3 decreased from 3.15 eV to 2.85 eV and 2.59 eV as the Al layer thickness increased from 100 to 150 nm, respectively. It is also observed that crystalline films of WO3 exhibited lower electrical resistivity compared to films fabricated by other techniques. The temperature dependent electrical resistivity measurement was carried out in the temperature range of 310-420 K. It showed room temperature values of 2.5 (Ωcm), 2.2 (Ωcm) and 1.9 (Ωcm) and impurity levels centered at 0.25 eV, 0.34 eV and 0.16 eV for uncoated and films coated with Al nanosheets of thicknesses of 100 nm and 150 nm, respectively. The enhanced crystallinity that is accompanied with narrower energy band gap and lower electrical resistivity values make crystalline WO3 films promising for optoelectronic applications.

“…The results indicated that the hybrid mode exhibited very low propagating loss and ultra-high figure of merit [24]. In addition, a structure involving plasmonic Al nanospheres randomly embedded within a perovskite solar cell was studied, and the enhancement of the optical absorption and optical carrier generation rate of the proposed perovskite cell was reported [25]. A bimetallic glucose sensor consisting of three-dimensional metal halide perovskites and two-dimensional material was proposed, its surface plasmon properties were investigated, and an improvement of characteristics for the perovskite-based SPR sensor was reported [26].…”

This work reports on the plasmonic properties of composite arrays consisting of graphene nanoribbons and perovskite nanowires, in the mid infrared region of 5 - 60 um. In the array, a set of graphene nanoribbons are placed on the perovskite nanowires, which are embedded in a glass substrate. Two scenarios are investigated in this work; one is that the graphene and the perovskite are matched, while the other is that the graphene and the perovskite are mismatched. The light transmittance of the arrays is numerically simulated, via the finite difference time domain method. Multiple plasmonic resonances are observed, and the corresponding electric field distributions are calculated. The results demonstrate that the plasmonic characteristics of the arrays can be adjusted by varying the parameters including the chemical potential and the layer number of graphene, as well as the refractive index of perovskite, etc. In addition, a Fano lineshape is revealed in one of the resonance peaks of the transmittance. It is well fitted to the Beutler-Fano formula, and the characteristic $q$ factor is determined. The results in this work may be useful in studies of similar plasmonic nanostructures that employ graphene and perovskite-based composite nanoarrays.
