“…Finally, interesting effects have also been observed in the field of plasmo-mechanics where mechanical stress is introduced into the THz devices. [60][61][62][63] Even though the miniaturization trend, illustrated in FIG. 1a, cannot be sustained any longer, market still needs performance enhancement beyond improvement delivered by scaling.…”

Semiconductor industry is experiencing unprecedented growth, still driven by Moore's law, which is continually delivering devices with improved performance at lower costs. The continuation of this development places the industry in a divergent trade-off between economic attractiveness, technological feasibility, and the need for further performance improvement. Since the mainstream semiconductor technologies are silicon-based, new disruptive innovations are needed to gain additional performance margins. The use of nanowires is the preferred approach for preserving electrostatic control in the MOS transistor channel, and the application of mechanical stress is a booster of carrier mobility. It is in this context that this paper presents the design, fabrication, theoretical modeling, and characterization of a measurement platform to characterize the mechanical tensile stress of extremely narrow Si nanowires as small as 14.2 ± 1.12 nm in width. The proposed measurement platform enables a precise control of uniaxial strain, in terms of both amplitude and location, through the implementation of a stoichiometric Si3N4 pulling strand exerting a high tensile force on silicon nanowires. Reported devices are fabricated using a silicon-on-insulator wafer with fully complementary metal–oxide–semiconductor-compatible processing and top-down approach. It is observed that the mechanical strength of nanostructured Si is size-dependent and increases with miniaturization. Characterization revealed a record tensile strength value of 7.53 ± 0.8% (12.73 ± 1.35 GPa) for the narrowest nanowires fabricated using a top-down approach.

“…There has been a growing interest in two-dimensional (2D) materials since the first synthesis of graphene in 2004 [1][2][3][4][5][6][7][8][9][10]. Graphene is a one-atom-thick crystal of hexagonal arrangement of carbon atoms which has remarkable properties such as high electronic and thermal conductivities, quantum Hall effect, etc [11][12][13][14][15][16][17][18][19].…”

The controlling of the transmission in the pseudospin-one Dirac-Weyl systems oﬀers a rich tool to study new concepts of massive Dirac electron tunneling by means of a time-dependent potential. The time-periodic potential is one of the experimental techniques to have more control over the tunneling eﬀect. In this paper, we study the transmission coeﬃcient for diﬀerent sidebands to obtain total transmission. We show how the super Klein tunneling under special condition is independent of the incidence angle, oscillation amplitude, frequency, and barrier width. We consider a band gap opening with diﬀerent locations of the ﬂat band and modulate the resonances by tuning free parameters in our system.

been introduced into optoelectronic devices for the enhancement of chargecarrier generation. [21,22] LSP devices or structures working in the infrared [23][24][25] and in the terahertz spectra [26][27][28][29][30] are of special interest to different application fields. In such cases, micrometer-or even millimeter-scale structures have to be fabricated to accomplish the resonance in the target spectral range. On one hand, this will ease the fabrication techniques due to the much-lowered resolution requirements, on the other hand, large dimensions of the metallic structures also imply large loss, due to the large thickness of the structures for the optical field to transmit through. In particular, for the spectral range of near-infrared between 1 and 3 µm in wavelength, it is especially critical to control the structural sizes to achieve the resonance spectrum and to balance the optical loss properties. This spectral range is very important for a large variety of optoelectronic techniques and applications, including solar cells, photodetectors, light-emitting or lasing devices, sensors, or photo-actuators. However, LSPs in nanostructured metals are mostly working in the visible spectral range. Plasmonic nanoparticles, [30,31] nanospheres, [32,33] nanowires, [34,35] nanoholes, [36,37] nanorings, [38] or even more complexed nanopyramids, [39] nanostars, [40] and nanoflowers [41] have been reported. The sizes or the aspect ratios of the whole structure or some segments can be utilized as the dimensions for tuning the LSP resonance spectrum. [42][43][44][45] Using interfacial coupling between metallic nanostructures is an effective approach to redshift the LSP resonance spectrum. [46] Nevertheless, nanostructured metals with LSP resonance in the infrared are relatively less reported.In this work, we solve this challenge by constructing curve gold nanoshell (AuNS) cylindrical ridges, where the curved nanostructures not only extend largely the length of the plasmonic electron oscillation trajectory but also enhance the electronic scattering process by the strongly bent trace. Thus, the corresponding LSPs are tuned in the spectral range from 1.1 to beyond 2.5 µm simply by changing the perimeter length, the curvature angle, and the thickness of the AuNS cylindrical ridges. The photophysical mechanisms for such curved LSPs are verified both experimentally and theoretically.The construction of 3D localized surface plasmons (LSPs) in infrared using curved gold nanoshell (AuNS) cylindrical ridges is reported, where the LSPs are found to be established through electronic oscillation in curved trajectories along the perimeter of the cross-sectional profile of the AuNS cylindrical ridges. Such a design is equivalent to an extension of the electronic trajectory length or plasmonic electron-oscillation distance by the curvature length and by the enhanced electronic scattering. Strong LSPs are measured for the transverse magnetic polarization perpendicular to the extending direction of the AuNS cylindrical ridges in the spectral ra...
