3. 二维材料精确应变工程

发展基于“应力源”的应变场精确调控方法,实现二维材料中量子性能(如赝磁场)的按需分布;开展面向特定性能的反向“应力源”设计,为下一代高性能芯片研发提供理论支持。

4. 纳米复合结构力学与热输运性能调控

建立低维复合结构在力学载荷下的变形-组装耦合模型,结合声子热传导理论,预测并调控其导热行为;集成机器学习方法,实现复杂结构热性能的高效预测,服务于高性能芯片热管理设计。

5. 微纳尺度材料模拟计算方法

融合第一性原理计算(如QMC、DFT)与机器学习,发展高精度力场;通过理论比拟、粗粒化建模及等效力场等手段,构建兼顾精度与效率的大尺度分子动力学模拟框架,将模拟尺度提升至微米级空间与微秒级时间范围。
