项目摘要
Hybridization of reduced dimensionality with nontrivial geometry and topology in complex tree-dimensional semiconductor structures fabricated using the strain-driven roll-up technology is a rich source of new phonon physics. The project is devoted to theoretical modeling of the Brillouin-Mandelstam scattering (BMS) and validation of an experimental BMS platform for characterization of novel rolled-up micro- and nanoarchitectures.The proponents at the IIN, IFW Dresden possess recognized complementary expertise in their respective fields of micro- and nanoarchitectures: theoretical analysis (theory of phonon spectra in low-dimensional structures based on the elastodynamic theory and the Lattice Dynamics numerical approach), high-tech fabrication (strain-driven roll-up technology) and optical characterization. The experience available at the cooperating Phonon Optimized Engineered Materials Center (POEM), UC-Riverside will be important and helpful to boost establishing the BMS experimental platform at the IIN, IFW Dresden. Verification and interpretation of the obtained phonon spectra will be performed by comparing the calculations conducted at the IIN, IFW Dresden and in the group at the Moldova State University (MSU), Chisinau in continuation of their long-standing cooperation.A synergy of their research efforts will be the cornerstone for the success of the present project aimed at getting insight in the phonon-assisted phenomena in advanced micro- and nanoarchitectures and developing an effective tool of their characterization. The key goals of the present project are of major relevance to the combined advancements of both fundamental science and applicative scope of nanophononics.
在使用应变驱动卷起技术制造的复杂三维半导体结构中,降维与非平凡几何和拓扑的混合是新声子物理的丰富来源。该项目致力于布里渊-曼德尔散射(BMS)的理论建模和实验BMS平台的验证,用于表征新型卷起的微米和纳米架构。IIN,IFW Dresden的支持者在各自的微米和纳米架构领域拥有公认的互补专业知识:理论分析(基于弹性动力学理论和晶格动力学数值方法的低维结构中的声子谱理论),高科技制造(应变驱动卷起技术)和光学表征。在合作的声子优化工程材料中心(POEM),UC-Riverside提供的经验将是重要的,有助于促进在IIN,IFW德累斯顿建立BMS实验平台。将通过比较IIN、IFW Dresden和摩尔多瓦州立大学(MSU)小组进行的计算,对获得的声子谱进行验证和解释,基希讷乌继续他们的长期合作。他们的研究工作的协同作用将是本项目成功的基石,该项目旨在深入了解先进微电子技术中的声子辅助现象。和纳米结构,并开发一个有效的工具,他们的表征。本项目的主要目标与纳米声学的基础科学和应用范围的综合进步有关。
