Summary: Researchers have successfully grown two-dimensional arsenic allotropes on an insulating SiC substrate using molecular beam epitaxy. The arsenene has a flat structure and follows the periodicity of the SiC surface. Ab initio simulations based on density functional theory confirm the experimental observations. The strained structure exhibits a new triangular arsenene allotrope rather than the previously predicted honeycomb structure. This strained structure undergoes a Peierls-like transition, resulting in an indirect band gap semiconductor behavior.

Summary: The thermo-optic coefficient (TOC) of silicon-rich amorphous silicon carbide (a-SiC) thin film deposited by plasma-enhanced chemical vapor deposition (PECVD) was characterized in this work. It was found that the TOC increases with the silicon content of the film. The TOC showed a more than threefold improvement, reaching a value as high as 1.88 x 10-4 degrees C-1, comparable to crystalline silicon. An efficient thermo-optic phase shifter was demonstrated by integrating the silicon-rich a-SiC micro-ring structure with a NiCr heater, achieving a tunability of 0.117 nm/mW and a tuning efficiency P pi as low as 4.2 mW at an optical wavelength of 1550 nm. These findings suggest silicon-rich a-SiC as a promising material for thermo-optic applications in photonic integrated circuits.

Summary: Using ultrashort-pulse laser-induced plasma-assisted ablation on soda-lime glass, researchers developed SERS substrates with amorphous nanostructures and a silver layer, resulting in homogeneous SERS activity with consistent surface activity. The relatively modest enhancement factor was attributed to the amorphous features on the glass, which led to fewer hot spots but increased surface homogeneity. The use of soda-lime glass offers a cheaper and scalable alternative for routine SERS testing in various scientific fields.

Summary: An atmospheric non-thermal arc plasma source based on magnetically stabilized gliding arc discharge was developed for the continuous preparation of ultrafine amorphous silicon carbide (a-SiC) nanoparticles via hexamethyldisilane decomposition. The synthesized nanoparticles showed strong blue-green light emission and had abundant functional groups and oxidized overlayers on their surface. Low input energy favored the synthesis of a-SiC nanoparticles, while high input energy promoted the transition from amorphous structure to b-SiC.

Summary: This study synthesized B4C and SiC nanoparticles to prepare ultrafine-grained B4C-SiC ceramics and systematically investigated the effect of grain size on the mechanical properties of the composites. It was found that residual stress emerged in the B4C-SiC interface as B4C grains reached a nanostructured state, improving the toughness significantly to 5.13 MPa m1/2. The B4C-SiC composite also exhibited excellent hardness of 36.6 GPa, surpassing that of monolithic B4C ceramics. This study has important implications for the development of toughening mechanisms for B4C-SiC ceramics and presents a new strategy for producing high-performance ceramics.
