“…Similar non-monotonic effects of proton irradiation are commonly found in the literature 31 , 33 , 34 , 44 – 46 . In the Ni 48·4 Mn 28.8 Ga 22.8 film irradiated with 120 keV protons 45 , the M S for ϕ = 10 15 cm −2 raised to 155% of the non-irradiated sample’s value, but for ϕ = 2 × 10 16 cm −2 , the observed M S was only 102%.…”

The influence of 1.9 MeV proton irradiation on structural and magnetic properties has been explored in the two-dimensional (2D) NiSO4(1,3-phenylenediamine)2 coordination ferrimagnet. The X-ray powder diffraction and IR spectroscopy revealed that the octahedrons with Ni ion in the center remain unchanged regardless of the fluence a sample received. In contrast, proton irradiation greatly influences the hydrogen bonds in the flexible parts in which the 1,3-phenylenediamine is involved. Dc magnetic measurements revealed that several magnetic properties were modified with proton irradiation. The isothermal magnetization measured at T = 2.0 K varied with the proton dose, achieving a 50% increase in magnetization in the highest measured field µ0Hdc = 7 T or a 25% decrease in remanence. The most significant change was observed for the coercive field, which was reduced by 90% compared to the non-irradiated sample. The observed results are accounted for the increased freedom of magnetic moments rotation and the modification of intralayer exchange couplings.

“…Ion beam irradiation, thermal annealing, electron beam irradiation, α-particle irradiation, ozone treatment, laser irradiation, , electrochemical desulfurization, proton irradiation, and plasma treatment are some examples of ex-situ methods and post-treatments to create defects in 2D TMDs. Chemical reduction via reducing agents or solvents, , vacuum activation, and lithium-induced conversion , are other practical methods to induce defects not only in TMDs but also in other materials.…”

Two-dimensional transition metal dichalcogenides (TMDs) offer fascinating opportunities for fundamental nanoscale science and various technological applications. They are a promising platform for next generation optoelectronics and energy harvesting devices due to their exceptional characteristics at the nanoscale, such as tunable bandgap and strong light-matter interactions. The performance of TMD-based devices is mainly governed by the structure, composition, size, defects, and the state of their interfaces. Many properties of TMDs are influenced by the method of synthesis so numerous studies have focused on processing high-quality TMDs with controlled physicochemical properties. Plasma-based methods are cost-effective, well controllable, and scalable techniques that have recently attracted researchers' interest in the synthesis and modification of 2D TMDs. TMDs' reactivity toward plasma offers numerous opportunities to modify the surface of TMDs, including functionalization, defect engineering, doping, oxidation, phase engineering, etching, healing, morphological changes, and altering the surface energy. Here we comprehensively review all roles of plasma in the realm of TMDs. The fundamental science behind plasma processing and modification of TMDs and their applications in different fields are presented and discussed. Future perspectives and challenges are highlighted to demonstrate the prominence of TMDs and the importance of surface engineering in next-generation optoelectronic applications.

“…Therefore, this study focuses on the creation of antisite defects with low-energy proton irradiation, the precise atomic characterization of low-energy radiation-induced defects, and the linkage between these defects and their effects on the properties of MoS 2 through defect engineering. While proton irradiation effects on the electrical properties of MoS 2 have been studied extensively, ,− less is known about the optical, chemical, and morphological characteristics of MoS 2 and WS 2 monolayers. Unfortunately, most of the existing studies were conducted for higher energies of proton irradiation (1–10 MeV). ,, There are even fewer studies about proton irradiated WS 2 . ,, These previous studies are summarized in Table , and it is noteworthy that most of these studies were conducted on mechanically exfoliated samples at higher energies without a comprehensive defect analysis.…”
