Layered crystal embeds atom-thin iron selenide can improve waste heat conversion

Дата публикации: 17-07-2026 17:20:01

Developing thermoelectric materials that efficiently convert waste heat into electricity remains challenging because high electrical performance and low thermal conductivity are difficult to achieve simultaneously. Researchers at Science Tokyo developed a layered crystal, TlFe1.6Se2, that embeds atomically thin iron selenide (FeSe) layers within a bulk material. The crystal combines a high thermoelectric power factor with exceptionally low thermal conductivity, demonstrating a promising strategy for designing next-generation materials for waste heat energy recovery.
