“…The SRIM-2013 [39] calculation of H + irradiation was performed on Zr/Nb multilayered systems with individual layer thicknesses of 25 nm and 100 nm and a total thickness of 1 µm ( Figure 2). The simulation was carried out using ion distribution and a quick calculation of damage mode with perpendicular 900 keV H + beam, where the total number of incident particles was 5 × 10 5 . The presence of an 11 µm aluminum energy degrader was taken into account.…”

“…Radiation-induced defects and the corresponding changes in mechanical properties in irradiated materials have been carefully studied in recent decades for various multilayer coatings [1][2][3][4][5][6][7]. These structures with various crystal structures are widely used as self-healing coatings in radiation point defects, where vacancies and interstitials can recombine [8][9][10][11].…”

Nanoscale multilayer coatings (NMCs) with different crystal structures are considered as capable of self-healing after radiation damage due to the recombination of vacancies and interstitials. This work is focused on a defect distribution study of NMCs based on Zr/Nb layers (25/25 nm and 100/100 nm) after proton irradiation. Coatings with a total thickness of 1.05 ± 0.05 µm were irradiated by 900-keV protons using a pelletron-type electrostatic accelerator with an ion current of 2 µA for durations of 60 min to 120 min. The influence of the irradiation effect was studied by X-ray diffraction analysis (XRD), glow discharge optical emission spectrometry (GD–OES), and Doppler broadening spectroscopy using a variable energy positron beam. The results obtained by these methods are compatible and indicate that defect concentration of Zr/Nb NMCs remains unchanged or slightly decreases with increasing irradiation time.

TiN and ZrN are emerging as important alternative plasmonic materials. In addition to their well-known assets, they can incorporate point defects that break the centrosymmetry of their cubic crystal structure, making them promising candidates as non-linear optical materials and especially for second harmonic generation (SHG). Their refractory character and chemical stability were obstacles for the bottom-up fabrication of TiN and ZrN nanostructures so far. In this work, it is shown that highly directional dichroic nanostructures of TiN and ZrN may be indeed grown by self-assembly using glancing angle deposition on periodic rippled dielectric surfaces. The produced nitride nanostructures exhibit point defects and exceptional photothermal durability. These nanostructures exhibit strong SHG response when probed by a near-infrared laser. It is shown that SHG is strongly associated with the near-field enhancement due to the localized surface plasmon resonance of the nanostructures. Given that such nanostructures can endure extremely high electric fields, they are expected to be able to emit massive SHG signals and be applied in laser technology as optical components such as polarizers and SHG emitters.

Young’s modulus of the nc-TiN/a-Si3N4nanocomposite has been calculated depending on a size and a volume fraction of the nanocrystalline phase. The elastic moduli of a-Si3N4matrix and nc-TiN nanocrystals as well as their relation show that they play an important role in the total elastic modulus of the nanocomposite. The kinetics of the defect structure during nanocomposite irradiation was investigated taking into account the recombination processes and sinks on the nanocrystals.
