Abstract:	摘要： Graphene, which exhibits excellent thermal conductivity, is a potential heat dissipation medium for compact optoelectronic devices. Photonic devices normally produce large- quantity of unwanted heat, and thus, a heat dissipation strategy is urgently needed. In this study, single-layer graphene (SLG) grown by chemical vapor deposition (CVD) is used to cover the surface of a photonic crystal (PhC) cavity, where the heat flux produced by the PhC cavity can be efficiently dissipated along the in-plane direction of the SLG. The thermal properties of the graphene-capped PhC cavity were characterized by experiments and theoretical calculations. The thermal resistance of the SLG-capped PhC cavity obtained from experiments is lower than half of that of a bare PhC cavity. The temperature of a SLG-capped PhC cavity is 45 K lower than that without SLG capping under an optical power of 100 μW. Our simulation results indicate that SLG receives the majority of the heat fluxes from the device, leading to the efficient heat dissipation. Both the experimental and simulation results suggest that the SLG is a promising material to enhance the heat dissipation efficiency for optoelectronic applications. 其他題名： ACS Nano 出版者： United States: American Chemical Society 出版日期： 2013-12-23 出處： ACS Nano, 2013-12, Vol.7 (12), p.10818-10824 資源來源： American Chemical Society Journals 版權： Copyright © 2013 American Chemical Society 識別號： ISSN: 1936-0851 識別號： ISSN: 1936-086X 識別號： EISSN: 1936-086X 識別號： DOI: 10.1021/nn404097s 識別號： PMID: 24224797
