An investigation of the effects of ZnO inverse opal pore size in the composite of ZnO nanorods/ZnO inverse opal on the performance of quantum dot-sensitized solar cells

Abstract

A semiconductor oxide composite consisting of ZnO nanorods (NRs) and ZnO inverse opal (IO) was fabricated and used in the photoanode of quantum dot-sensitized solar cells (QDSSCs). Using polystyrene spheres...

Dynamically changeable terahertz metamaterial absorbers with intelligent switch and high sensitivity and wide and narrow band perfect absorption

“…S parameters can be written down as follows. 53 where, n and t represent the refractive index and the thickness of the absorber, respectively, and Z is the relative impedance whose calculation formula is as follows. 54 …”

Active thermally tunable and highly sensitive terahertz smart windows based on the combination of a metamaterial and phase change material

“…In this paper, the properties of VO 2 , a thermotropic phase change material, are characterised using the Drude model, as described in eqn (1), 23 where ε ∞ = 12 is the high frequency dielectric constant, which is the frequency of plasma oscillation dependent on electrical conductivity, as shown in eqn (2). The initial value of the plasma frequency ω P0 = 1.45 × 10 15 s −1 , σ 0 = 3 × 10 5 S m −1 , and the collision frequency is γ = 5.75 × 10 13 s −1 .…”

Highly sensitive plasmonic sensor based on eccentric-core photonic crystal fibers

“…Knight et al produced the first PCF based on the total reflection principle by drawing prefabricated rods in regular stacks. 30 In order to effectively introduce the SPR effect into optical fibers, thin films of a suitable thickness and uniform distribution need to be coated at suitable locations in the fibers, which requires the support of coating techniques, such as electron beam vapor deposition, 31 chemical vapor deposition, 32 and magnetron sputtering. 33 In order to effectively enhance the coupling strength of the core mode and SPP mode, and to remove the secondary processing of the fibers and reduce the difficulty of coating, an EC-PCF was designed.…”
