7月29日,华中科技大学光学与电子信息学院, 和丹麦技术大学的研究团队(丁运鸿,Leif Katsuo Oxenløwe,肖三水,左炎,严思琦)在期刊 Opto-Electronic Advances 发表题为 Graphene photodetector employing double slot structure with enhanced responsivity and large bandwidth 的论文。 Source:PubCard...
electronics12,13and wafer-scale synthesis13, graphene-based integrated electronic–photonic circuits with an operational wavelength range spanning 300 nm to 6 µm (and possibly beyond) can be expected in the future.
Graphene research so far has focused on electronic1,2,3,4,5,6 rather than photonic applications, in spite of its impressive optical properties7,8. These include its ability to absorb ∼2% of incident light over a broad wavelength range despite being ju
Here, we report the first use of a photodetector based on graphene, a two-dimensional carbon material, in a 10 Gbit s'1 optical data link. In this interdigitated metal€"graphene€"metal photodetector, an asymmetric metallization scheme is adopted to break the mirror symmetry of the ...
Here, we report an ultra-broadband photodetector design based on a graphene double-layer heterostructure. The detector is a phototransistor consisting of a pair of stacked graphene monolayers (top layer, gate; bottom layer, channel) separated by a thin tunnel barrier. Under optical illumination, ...
plasmonically enhanced graphene photodetector featuring 100 gbit/s data reception, high responsivity, and compact size eth libraryGraphene has shown great potential for high-speed photodetection. Yet, the responsivities of graphene-based high-... Ping,Ma,Yannick,... 被引量: 0发表: 2019年 Surface...
摘要: The responsivity of a monolayer graphene photodetector based on the photo-thermoelectric effect was measured at room temperature for dc, terahertz, and optical frequencies and found to be approximately 81, 188, and 18 V/W respectively....
Broadband high photoresponse graphene photodetector We demonstrate a high photoresponsivity of 8.61 A/W in pure monolayer graphene photodetectors, together with a broadband photoresponse from the visible to mid-infrared, through bandstructure engineering of graphene ...
