Revealing the 'true colors' of a single-atom layer of metal alloys
SMRTR summary
A thallium-lead alloy single-atom layer can restrict spin-polarized current to one direction when irradiated at room temperature, defying conventional understanding of light absorption in ultra-thin materials. This discovery enables potential breakthroughs in environmentally friendly data storage and ultra-fine two-dimensional spintronic devices, with implications for more efficient light-to-spin-polarized current conversion.
