Ferroelectric switching can directly invert dominant altermagnetic d-wave spin-momentum locking, providing a pure electrical and optical route to manipulate coexisting relativistic and non-relativistic spin textures.

Swapping a single boron atom for carbon breaks traditional electronic-thermal trade-offs, simultaneously opening a 0.33 eV semiconductor bandgap and boosting lattice thermal conductivity by 250%.
