KAIST team catches HZO memory films forming new domains while older ones spread

KAIST researchers imaged hafnium zirconium oxide memory films switching by two processes at once, with new polarized domains forming while existing ones grew. A model tying that picture to device electrical data offers a basis for tuning write speed and uniformity, though the account reports no switching times.

Baking sodium out of a boride leaves a porous boron 10 million times more conductive than common boron

Chemists baked the sodium out of sodium boride to make Imma-B60, a porous boron that conducts about 10 million times better than the common form. Its flexibility figure is shakier, given in the same report as both 23% and 32% strain, the higher from compressing nanopillars.
