“…The results show that compared to TzN-S based device, the TzS-S based device exhibits more efficient exciton dissociation and more effective charge collection. Therefore, due to better light absorption and higher production of excitons 38 in its active layer, the higher J sc and FF of the TzS-S based device is understandable.…”

“…This unit cell consists of a layer of dielectric material sandwiched between the metallic ground and upper metallic patches. Metamaterials are designed to obtain unique electromagnetic properties such as perfect absorbers [1], [2], [3], solar cells [4], [5], polarization control [6], [7], and sensors [8], [9]. Tiny changes in the surroundings of the metamaterial sensor cause a variation in the electromagnetic response like optical absorption and resonance frequency.…”

Abstract-Highly sensitive triple-band metamaterial-based biosensor for different cancer cells detection is suggested and numerically analyzed. The reported sensor has a polyimide dielectric layer which is sandwiched between gold bottom plane and top metallic patches. The analyte sample covers the metallic patch where multiple resonances occur with high absorption. The resonance frequencies depend on the optical properties of the analyte sample. Therefore, the proposed sensor can distinguish between different cancer cell types such as skin cancer, blood cancer, and Breast cancer. Full vectorial finite element method is used to study the effects of the geometrical parameters with the aim to maximize the sensor sensitivity. The suggested sensor has high sensitivity of 2050 GHz/RIU (which is much higher than those suggested in the literature) with high quality factor of 55.34 in the frequency range from 4.25 THz to 4.75 THz. Further, the proposed biosensor is a label-free, and easy for fabrication using the state-of-the-art fabrication technologies.

Hyperbolic metamaterials (HMMs) are known for their robust light–matter interaction and ability to generate volume plasmon polaritons (VPPs). Au nanoparticles (Au NPs) enable to enhance this interaction through localized surface plasmon resonance (LSPR), creating intense local electric fields. However, combining LSPR and VPPs in one device remains unexplored. This study proposes and demonstrates Au NP‐coupled‐HMMs (NPCHMMs), integrating Au NPs with HMMs to enhance random laser action and lower the lasing threshold. NPCHMMs boost emission intensity by ≈6 times compared to pure HMMs, with a ≈47% reduction in lasing threshold. Based on Fermi's golden rule, the calculated transition rate in NPCHMMs surpasses the algebraic sum of the individual transition rates derived from HMMs and Au NPs. It reveals the effect of the coherent coupling between the transition matrix elements of VPP and LSPR. This research indicates that NPCHMMs are a promising platform to create high‐performance optical and optoelectronic devices, such as lasers and phototransistors, for a wide range of application in many fields.
