Summary: The study identifies a unique self-modulated doping characteristic in 2D layered materials, allowing for controlled tuning of p-type, intrinsic, and n-type doping in the same material through thickness modulation. Lattice deformation in PtSSe transitions defects from Pt vacancies to anion vacancies, leading to different types of conductance. By modulating thickness, the WSe2 diode demonstrates high rectification ratio and open-circuit voltage, while the PtSSe detector overcomes the issue of large dark current in narrow-bandgap optoelectronic devices. These findings offer a fresh perspective for both fundamental scientific research and practical applications.

Summary: In this study, we investigated the spin/valley polarization dynamics of excitons in 2D transition metal dichalcogenides (TMDCs) and their heterojunction with graphene. Our findings revealed that the dynamics exhibit a biexponential decay and are influenced by ultrafast intervalley electron-hole spin-flip exchange coupling, electron-phonon scattering, and recombination and relaxation of trion states. Additionally, the presence of graphene in the heterojunction prevents the formation of trions, leading to a faster relaxation process for the excitons.

Summary: Nanopore-rich NiFe LDH (PR-NiFe LDH) nanosheets were proposed as a catalyst for enhancing the oxygen evolution reaction (OER) activity and stability. By creating abundant unsaturated Ni sites and decreasing the migration distance of protons, the catalyst promotes the formation of high-valent active sites. The unique structure also improves the stability of OER. The optimized PR-NiFe LDH catalysts exhibit excellent electrocatalytic performance and show good stability in anion exchange membrane (AEM) water electrolyzer devices.

Summary: By utilizing γ-butyrolactone (GBL) as an organic solvent, the deposition behavior and performance of Zn anodes can be regulated, allowing for improved electrochemical performance under high current densities and large areal capacities due to reduced dendrite growth and enhanced reaction reversibility. The strong interactions between GBL molecules and Zn2+ and Zn slab were confirmed by DFT calculations, and the preferential adsorption of GBL at the Zn/electrolyte interface was highlighted through Raman spectra analysis. Electrochemical tests demonstrated the effectiveness of this strategy, achieving a supporting current density of 30 mA cm(-1) and a cycle life of 5000 h for the Zn anode using GBL.
