Summary: In this study, a binder-free bismuth (Bi) anode was developed, based on the one-step electrochemical codeposition of three-dimensional Bi nanosheets and conductive carbon nanotube networks (Bi NS/CNTs). The co-deposition of these structures enabled strong interfacial adhesion and accommodation of volume change during cycling, leading to long-term cycling stability and good rate performance. When assembled into a full sodium-ion battery with a Na3(VOPO4)2F@rGO cathode, the Bi NS/CNTs anode exhibited a high operating voltage and energy density, outperforming other reported Bi-based analogues. This work presents a new opportunity for developing efficient sodium-ion batteries with high energy and practicality.

Summary: The breakdown characteristics of AlGaN/GaN high-electron-mobility transistors are crucial for their practical applications. This study investigated the relationship between the relative permittivity of passivation layers and the breakdown voltages. An embedded double-passivation layer was proposed to enhance the breakdown voltage of the devices. The findings show that adjusting the relative permittivity can greatly improve the breakdown voltage, and a greater difference in dielectric constants leads to higher breakdown voltages.

Summary: A phase engineering strategy aided by resonant plasmonic coupling is proposed to manipulate the valley degree of freedom in transition metal dichalcogenides. Through the designed plasmonic array, the hybrid phase WSe2 exhibits enhanced circular polarization and valley polarization. Finite difference time domain simulations demonstrate consistent polarization effects between theory and experiment. The high polarizations are attributed to increased exciton generation and radiation efficiency, chiral electromagnetic field, and non-equilibrium spin distribution in the hybrid phase.
