Using atomic-resolution scanning transmission electron microscopy, researchers found that in the presence of iron, the grain boundary of titanium undergoes a phase transition, forming “cages” or “clusters” at the grain boundary (the gold region at the center of the image).

When Iron Meets Titanium: Discovery Oof Quasicrystalline-Like Grain Boundary Phases In Alloys

The interfaces between individual crystals in a material, known as grain boundaries (GBs), play a critical role in dictating the strength, durability, and overall performance of a material. For this reason, GB phase transitions —…

NRL research team develops a new method to control single photon emission using a hybrid ferroelectric heterostructure. The character of light emitted from an atomic scale emitter in a monolayer semiconductor, WS2, is controlled by the ferroelectric polarization in an adjacent film. Localized emitters in the monolayer WS2 over “up-domains” in the ferroelectric film emit high purity quantum light, while those over “down-domains” emit semi-classical light. This modulation offers an additional tool for secure communications and quantum encryption schemes based upon single photon sources.
