University researchers set world record for fast, efficient data center LED

Researchers demonstrate optimal micro-LED size at 5 micrometers through systematic scaling study

2 Oct 31 · 12d ago · 2 posts · 1 source · development 2 of 2

The team systematically scaled down micro-LED devices from 100 micrometers to 2 micrometers in diameter, discovering that the optimal performance point was at 5 micrometers—contradicting assumptions that smaller is always better. This scaling work provides a development roadmap for balancing size, bandwidth, and power consumption tradeoffs.

“We found that, contrary to popular belief, smaller is not always better. Our work gives a development roadmap to systematically study the tradeoffs between size, bandwidth and power consumption.”
