项目摘要

The objective of this program is to investigate the effect of rotation angle on the thermal conductivity of twisted bilayer graphene. The experimental and theoretical evidence is clear that the electronic states of the individual layers in twisted bilayer graphene are decoupled. The effect of the twist angle on the phonon dispersion is still an open question, and the effect of twist angle on the in-plane thermal transport has yet to be studied. These questions are intimately related since the heat is carried by the phonons. If the phonon coupling in twisted graphene layers were suppressed, then the multi-layer twisted graphene films would have enhanced thermal conductivity of single 2D layers acting in parallel, thus allowing for transfer of extraordinary large heat fluxes. The intellectual merit of this program is in creating fundamental knowledge determining the relation of twist angle to the thermal conductivity of bilayer graphene. The possibility of maintaining 2D properties of graphene in bulk materials through the use of misoriented stacking is a transformational concept giving us the best of both worlds ? the enhanced performance of 2D combined with the capacity of 3D.The broader impact the project includes new applications of graphene for thermal management. It has the potential to increase the US technological competitiveness. It will increase the participation of women and underrepresented minorities and contribute to undergraduate and graduate STEM education at UC Riverside, which is the minority serving institution with the largest Hispanic student population among all UC campuses. This project is jointly funded by the Electronics, Photonics, and Magnetic Devices Program (EPMD) in the Division of Electrical, Communications and Cyber Systems (ECCS) and by the Electronic and Photonic Materials Program (EPM) in the Division of Materials Research (DMR).
本程序的目的是研究旋转角度对扭曲双层石墨烯导热性的影响。实验和理论证据清楚地表明,扭曲双层石墨烯中各层的电子态是去耦的。扭转角对声子色散的影响仍然是一个悬而未决的问题,扭转角对平面内热输运的影响还有待研究。这些问题密切相关,因为热量是由声子携带的。如果扭曲石墨烯层中的声子耦合被抑制,那么多层扭曲石墨烯薄膜将增强平行作用的单二维层的导热性,从而允许传递非常大的热流。这个项目的智力价值在于创造了决定扭曲角与双层石墨烯导热性关系的基础知识。在块状材料中,通过使用错取向堆叠来保持石墨烯二维特性的可能性是一个革命性的概念,给我们带来了两全其美的效果。增强的2D性能与3D的容量相结合。该项目更广泛的影响包括石墨烯在热管理方面的新应用。它有可能提高美国的技术竞争力。它将增加女性和未被充分代表的少数族裔的参与,并为加州大学河滨分校的本科和研究生STEM教育做出贡献,河滨分校是加州大学所有校区中拥有最多西班牙裔学生的少数族裔服务机构。该项目由电气、通信和网络系统部(ECCS)的电子、光子学和磁性器件计划(EPMD)和材料研究部(DMR)的电子和光子材料计划(EPM)共同资助。
