Modeling of strain effect on thermal and electrical transport properties of Si/Ge nanocomposites and its applications

摘要: Nanocomposites are composite materials which incorporate nanosized particles, platelets or fibers. The addition of phases into the bulk matrix can lead to significantly improved material properties compared their macrocomposite counterparts. Due extraordinary properties, nanocomposites promise new applications in many fields such as ultra-high strength and ultra-light automotive parts, nonlinear optics, biomedical applications, sensors actuators, thermoelectric devices. design fabrication nanocomposite structures, devices systems be accelerated by developing accurate efficient computational tools that describe behavior nanocomposites. However, development is challenging due multi-scale nature materials. In addition, where employed multi-physics with interactions mechanical, thermal electrical energy domains. systems, while mechanical deformation dependent on temperature change, transport functions strain. this work, we develop theoretical models address these issues investigate strain effect Si/Ge
