加州大學洛杉磯分校(UCLA)薩謬埃里工程學院的研究人員的一項突破性發現，將有望改變電子產品的未來。
A groundbreaking discovery by researchers at the UCLA Samueli School of Engineering is set to transform the future of electronics.
該研究發表在《自然-物理學》(Nature Physics)期刊上，揭示了熱量在室溫下能以條理分明、如射線般的路徑穿過固體材料，這種現象被稱為「聲子聚焦」(phonon focusing)。
Published in Nature Physics, the study reveals that heat can travel in organized, ray-like paths through solid materials at room temperature, a phenomenon known as 'phonon focusing.'
透過利用一種獨特的結晶半導體——砷化硼(boron arsenide)，科學家們成功地在日常環境條件下維持了這些聚焦的路徑。
By utilizing boron arsenide, a unique crystalline semiconductor, scientists have managed to maintain these focused paths even in everyday conditions.
這是一項重大突破，因為熱量通常會隨機擴散，導致現代科技產品出現效能瓶頸。
This is a major leap forward because heat usually spreads randomly, causing performance bottlenecks in modern technology like AI hardware and smartphones.
有了這項發現，熱量現在可以沿著特定的、由晶體定義的路線被引導——就像光纖電纜引導光線一樣。
With this discovery, heat can now be steered along specific, crystal-defined routes—much like fiber-optic cables guide light.
這種以奈米級精度引導熱量的能力，實現了「量子熱工程」(quantum thermal engineering)。
This ability to direct heat with nanoscale precision allows for 'quantum thermal engineering.'
透過更有效地將熱量從敏感元件中移出，工程師現在可以設計出速度更快、更可靠且具能源效率的晶片。
By moving heat away from sensitive components more efficiently, engineers can now design chips that are faster, more reliable, and energy-efficient.
這項研究由胡永杰(Yongjie Hu)教授領導，確立了控制熱能的新典範，並可能為下一代高效能裝置鋪路。
Led by Professor Yongjie Hu, this research establishes a new paradigm for controlling thermal energy, potentially allowing for the next generation of high-performance devices.
