Bao Hua's group at JI achieves ultra-efficient phonon BTE solution and full-scale thermal simulation of transistors

Recently, Bao Hua's team from JI, Shanghai Jiao Tong University, published an online paper entitled "Ultra-efficient and parameter-free computation of submicron thermal transport with phonon Boltzmann transport equation" in the English journal "Fundamental Research" sponsored by the National Natural Science Foundation of China ( Research paper on Ultra-Efficient Parameter-Free Calculation of Heat Transport at Submicron Scale Based on Phonon-Boltzmann Transport Equation)

When the transistor is working, the internal moving electrons and lattice scattering will generate a lot of heat, and the "thermal bottleneck" is an important bottleneck restricting the further efficient integration of electronic devices and the improvement of chip computing efficiency

After years of research and exploration, and through interdisciplinary cooperation with the research group of JI teacher Shen Yongxing, Bao Hua's group has made a breakthrough in the efficient solution of phonon BTE.

Baohua is the corresponding author of the paper, and Hu Yue, a doctoral student at the JI, is the first author
