Tuning the Charge Transfer of Transition Metal Dichalcogenides via Misfit Layer Compounds

This study demonstrates that misfit layer compounds, specifically (LaxPb1-xSe)1.14(NbSe2)2, serve as a versatile platform for precisely tuning electron doping in NbSe2 monolayers through chemical alloying of the rocksalt layer, thereby enabling the engineering of emergent states in 2D transition metal dichalcogenides while preserving their intrinsic electronic structure.

Defect Control via Cu Enrichment Enhances Multifunctional Properties in the Polar Semiconductor Cu1+xMn1-ySiTe3

This study demonstrates that enriching the polar semiconductor Cu1+xMn1-ySiTe3 with copper effectively suppresses stacking faults, thereby unlocking enhanced second-harmonic generation, distinct spin-flop magnetic transitions, and doped semiconducting behavior that were previously hindered by crystal defects in Cu-deficient compositions.

Self-trapped holes and acceptor impurities in orthorhombic Ga2O3

This study utilizes hybrid density functional theory to demonstrate that self-trapped holes in orthorhombic κ\kappa-Ga2_2O3_3 are energetically favorable and stabilized by acceptor dopants, creating localized gap states that induce red-shifted optical absorption and suggest a potential pathway for achieving p-type conductivity through isoelectronic doping if self-compensation can be mitigated.
