Summary: Molybdenum diselenide (MoSe2) is considered a promising electrocatalyst for the hydrogen evolution reaction (HER), but its catalytic performance is hindered by inferior electrical conductivity and insufficient active sites. In this study, MoSe2@N-doped carbon (NC) hollow nanoflowers were successfully fabricated, improving the HER performance and highlighting the critical role of interfacial chemical bonds in regulating the electronic structure of nanomaterials.

Summary: Atomically thin semiconductors offer an attractive platform for quantum emitters, although reported quantum emitters in these materials have relied on spin-forbidden transitions. By employing strain confinement in monolayer MoSe2, engineered quantum emitters with radiative rates exceeding those of other solid-state systems have been produced.

Summary: Molybdenum diselenide (MoSe2) is gaining more attention for its natural abundance, larger interlayer space, and higher theoretical capacity, but its application is hindered by low capacity and poor cycling stability. The MoSe2/C nanoplates sheathed in N-doped carbon (MoSe2/C@NC) microstructures synthesized in this study show excellent reversible sodium/potassium ion storage capacity. The unique assembly structure of MoSe2/C@NC contributes to the synergistic effect, effectively alleviating volume expansion and improving electrical conductivity.

Summary: 2D materials, with easily tunable carrier type and concentration, show great potential in electronic and optoelectronic applications, but still require further improvement for practical use. Through substitutional doping of Ta atoms, p-type MoSe2 was successfully achieved, leading to the fabrication of outstanding homojunction photodetectors and inverters. The devices demonstrate high rectification ratio, large open-circuit voltage, and exceptional responsivity and efficiency, laying a foundation for the practical application of 2D material devices.

Summary: Hyperspectral imaging at cryogenic temperatures was used to study the propagation of excitons and trions in MoSe2 monolayers encapsulated with hBN. Differences in the spatial distribution of these particles were observed at high excitation densities, with trions showing a halo shape and excitons only exhibiting moderate broadening. Numerical simulations suggest that the discrepancy in profiles is due to the distinct lifetimes of the two quasiparticles.
