Summary: The phase transition mechanism of single- and bilayer MoS2 induced by lithium intercalation has been systematically studied using first principles. It is found that lithium intercalation can effectively reduce the sliding barrier of the S atom layer. The phase transition in bilayer MoS2 is induced by S atom transition one by one, and consists of the formation, diffusion, and recombination of S vacancies. The phase transition originates from interlayer lithium defects, while monolayer MoS2 cannot undergo phase transition due to the larger sliding barrier of the S atom.

Summary: Heterostructures can emerge in twisted bilayers of phosphorene, leading to energy and charge transfer within the plane. The formation of moire superlattices and electronic anisotropy in phosphorene results in one-dimensional moire excitons with unique properties. Low-frequency moire phonons and dynamic moire potentials play a crucial role in in-plane energy/charge transfer and exciton dynamics. These one-dimensional moire excitons are predicted to undergo Bose-Einstein condensation and could potentially form exotic Tonks-Girardeau Bose gases.

Summary: By performing first-principle transport calculations, lateral heterostructures of zigzag phosphorene nanoribbons (ZPNRs) with different passivated edges are proposed as a powerful platform for high-performance field-effect transistors (FETs). The H-passivated ZPNR exhibits semiconductor characteristics with a band gap of 1.39 eV, while ZPNRs with zigzag or cliff edges show metallic behavior. Transistors based on these structures can overcome the short channel effect, with the potential for high performance outlined by the International Technology Roadmap for Semiconductors.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
