A study led by researchers from Shanghai Jiaotong University addresses key challenges in phonon-based heat simulations for nanoscale devices. Traditional models struggle to simulate heat transfer accurately at this scale due to the dominance of phonons. The team developed a novel method that eliminates the need for empirical parameters by using first-principles calculations, significantly improving the model’s adaptability and accuracy. The method also introduces advanced numerical algorithms, dramatically increasing simulation efficiency. The work could greatly enhance thermal management in nanoelectronics and related fields.
