“…An intriguing observation is that the bandgap of these nanoribbons undergoes a significant reduction, transitioning from the eV scale to the realm of just a few meV. This phenomenon underscores the adaptability of these nanoribbon systems, mainly in contexts where extremely small bandgaps are required, such as in the domains of photonics and plasmonics, to operate at THz frequencies [41][42][43].…”

The quest for novel materials with extraordinary electronic and plasmonic properties is an ongoing pursuit in the field of materials science. The dataset provides the results of a computational study that used ab initio and semi-analytical computations to model freestanding nanosystems. We delve into the world of ribbon-like materials, specifically graphene nanoribbons, silicene nanoribbons, and germanene nanoribbons, comparing their electronic and plasmonic characteristics. Our research reveals a myriad of insights, from the tunability of band structures and the influence of an atomic number on electronic properties to the adaptability of nanoribbons for optoelectronic applications. Further, we uncover the promise of these materials for biosensing, demonstrating their plasmon frequency tunability based on charge density and Fermi velocity modification. Our findings not only expand the understanding of these quasi-1D materials but also open new avenues for the development of cutting-edge devices and technologies. This data presentation holds immense potential for future advancements in electronics, optics, and molecular sensing.

“…From theoretical or experimental studies, many researchers have found that PNRs exhibit superior properties in terms of their transport, thermoelectricity and optical behavior. [16][17][18] Edge effects can be observed in PNRs, which can affect their electronic structure and play an important role in their magnetic, optical, and transport properties. 19,20 It is worth noting that the pristine zPNRs have edge states, whereas the pristine aPNRs do not.…”

“…Using micro-and nano-structures with characteristic lengths smaller than or close to the wavelength of incident light [5], it is also possible to achieve special physical properties that traditional materials do not have, such as negative refractive index [6,7], negative magnetic permeability [8], negative dielectric constant [9], etc. Thus, micro-and nano-structure-based materials (including metamaterials) are potentially useful in stealth camouflage [9,10], polarization detection [11], perfect absorber [12], super-lenses [13], nano-heater [14], anti-icing effects [15], and so on.…”

We numerically investigated a dual-band metamaterial absorber based on the combination of plasmonic resonance and Fabry–Pérot (FP) resonance, which can achieve near-unity absorption for guided lasers. The absorber is constructed by a three-layer metal-insulator-metal (MIM) periodic configuration. In each unit cell, there is a gold-silicon cross on a thin silicon layer and a bottom nickel film. Numerical results show that, at normal incidence, the structure strongly absorbs light at wavelengths of 1.064 μm and 10.6 μm, with absorption rates higher than 94%. It is revealed that the two absorption peaks result from FP resonance in the thin silicon layer and plasmonic resonance in the cross, respectively. In addition, the absorber is polarization insensitive and is tolerant to the incident angle. The proposed combination of different resonances has the advantage of easily producing double absorption peaks with very large wavelength differences, and provides a new approach to the design of metamaterial absorbers.
