This work is devoted to the study of the formation of periodic relief on the InP surface during ion sputtering by bismuth ions with an energy of 30 keV and an angle of incidence of 45° respect to normal incidence. We compared the reliefs formed by sputtering with atomic and cluster bismuth ions, as well as the relief appearing on the surface of the sample irradiated at elevated temperature (290 °C). Three different types of reliefs were found: surface waves with nanodots on the surface “waves”, nanodots with uniform distribution and relief in the form of columnar micro crystallites during sputtering of a heated target. With increasing irradiation dose, insignificant changes in characteristic surface dimensions were observed for all three reliefs. Based on the nonlinear character of surface sputtering (“thermal spot” sputtering mode), we described the formation of relief in the form of nano-dots and in the form of micro crystallites as a result of local melting areas formation and subsequent solidification (crystallization) on the target surface. Regarding wave relief, in our opinion, an adequate physical description is given by a model based on the stress driven dynamics of ion irradiated surface.

“…A new signal, usually associated with indium oxide, is also can be noted in the 140-150 cm −1 region. The latter suggests that part of the nanodots on the surface has a layer of metallic indium with a thin oxide film formed in air during the transfer of the sample from one device to another [14][15][16].…”

“…As a result, a surface's contact angle may be controlled favorably by adjusting both the surface energy and the physical roughness. According to this correlation, wettable surfaces get wetter as surface roughness increases, while repellent surfaces become more repellent [39][40][41].…”

Introduction: This study focuses on the detection of rhodamine-6G using surface-enhanced Raman scattering (SERS) on gold nanostructures (AuNS) of different sizes. Ion beam irradiation has been carried out to tune the size of AuNS and investigate the underlying mechanisms of sputtering and diffusion that govern their growth. Additionally, the study established a correlation between fractal growth parameters, water contact angle, and SERS detection of R6G. The results of this study offer new insights into the mechanisms of SERS detection on roughened metallic surfaces.Methods: Thermal evaporation was used to deposit an Au thin film on a glass substrate. Subsequent 10 keV Ar+ irradiation was done on Au thin film for fluences ranging from 3×1014 to 3×1016 ions/cm2 to tune the size of AuNS. Rutherford backscattering spectroscopy (RBS) was used to confirm that the decrease in Au concentration under ion beam sputtering was responsible for the tuning in size and structure of AuNS. Fractal dimension (Df) and interface width (w) were used as statistical parameters to control the wettable characteristics of the AuNS surfaces.Results and discussion: The researchers found that the growth of AuNS was governed by ion beam induced sputtering and diffusion mechanisms. They established a correlation between fractal growth parameters, water contact angle, and SERS detection of R6G. They found that a higher surface coverage area of Au NPs with lower fractal dimensions and water contact angles favoured the SERS detection of R6G. This study provides new insights into the mechanisms of SERS detection on roughened metallic surfaces. It is found that the growth of AuNS was governed by ion beam-induced sputtering and diffusion mechanisms, and established a correlation between fractal growth parameters, water contact angle, and SERS detection of R6G. The findings of this study may have applications in the development of more sensitive and efficient SERS-based chemical sensors.

The nature of the growth rate due to streaming instability in a Semiconductor quantum plasma implanted with nanoparticles has been analyzed using the Quantum Hydrodynamic Model. In this study, the intriguing effect of temperature, beam electron speed, and electron-hole density on growth rate and frequency is investigated. The results show that the growth rate demonstrates a nonlinear behavior, strongly linked to the boron implantation, beam electron streaming speed and quantum correction factor. A noteworthy finding in this work is the discontinuous nature of the growth rate of streaming instability in boron implanted semiconducting plasma system. The implantation leads to a gap in the growth rate which further gets enhanced upon increase in concentration of implantation. This behavior is apparent only for a specific range of the ratio of thermal speed of the electrons to that of the holes.
