    Doping-Controlled Magnetism and Hyperpolarizability: Engineering Multifunctional 2D Quantum Dots Through Transition Metal-Phosphorus Hybridization.

    Preview:

    • Hollow-site reconstruction with pnictogen-TM environment in nonmagnetic host showed tunable spin texture.
    • Ternary configurations demonstrated enormous second-hyperpolarizability, large energy gaps, and spin dependent trap states.
    • The nested confinement results in a consistent distribution of orbitals with high spin polarization.

    Spin-Selective Orbital Reconfiguration and Nonlinear Anisotropy in Defect-Engineered Atomically Thin Quantum Dots.

    Preview:

    • Computationally shown that, alongside the spin degree of freedom, orbitals of different energies are spatially orthogonal and can be addressed independently.
    • Some of the orbitals with the same energy are highly symmetrical.
    • The second- and third-order static nonlinear responses exhibit phase-reversal behavior.
