High-performance p-type thin film made from Heusler alloy significantly improves capturing waste heat and cooling electronics

https://techxplore.com/news/2026-01-p-thin-power.html

"up to 4X more efficient converting heat into power than existing p-type thin films... equally capable p-type counterpart to n-type (both needed)... safe, low-cost... maximum 4.26 mWK−2m−1 power factor at 300 K, thickness-dependent with highest power factor in 500 nm film... future: overcome 600°C deposition cap for possible higher efficiency... solid-state cooling method for hardware, potentially reducing the reliance on energy-heavy fans and liquid cooling systems... data centers, factories"
