New nanowire LED offers higher efficiency and lower cost

Researchers at Lund University have engineered a new class of light‑emitting diodes (LEDs) that use thin, branched nanowires to enhance efficiency and reduce manufacturing costs. The team’s findings, published in the journal *Nano Research*, demonstrate that precise control over the location of light generation within the nanowire structure can significantly lower energy losses that typically limit LED performance.

The nanowire design allows light to be emitted from specific regions of the device, minimizing internal absorption and scattering that would otherwise waste photons. By tailoring the branching geometry and material composition, the researchers achieved a higher proportion of usable light output while maintaining a simple fabrication process. This approach could translate into LEDs that consume less power and are cheaper to produce compared to conventional planar devices.

If scalable, the technology offers a promising pathway toward more efficient lighting and display systems. The study provides a foundation for future work on integrating branched nanowire LEDs into commercial products, potentially advancing the broader adoption of sustainable illumination solutions.
