石墨烯以其特殊的结构和优异的光电性能被广泛用作纳米光学器件和传感器的基础材料。石墨烯由于其从紫外到太赫兹波段的超宽吸收光谱、载流子迁移率和超快的光反应速度而被认为是一种理想的光电探测器材料。在这项研究中，光热纳米器件使用石墨烯制成，石墨烯使用全干式粘弹性冲压方法转移到电极上。该纳米器件具有结构简单、效率高、可即时测量等优点。利用该纳米器件对石墨烯的光吸收进行了测量，计算出的石墨烯的光吸收率与以往的研究结果基本一致。不同波长的辐照和不同温度下的热加热实验表明，该纳米器件对近红外光和中红外光具有良好的响应。该结论为纳米器件的研究、设计和制作提供了实验依据，该器件可为电子元器件和太阳能电池等领域的光温探测提供有效的方法。
Graphene is widely used as the basic materials of nano optical devices and sensors on account of its special structures and excellent photoelectric properties. Graphene is considered as an ideal material for photodetectors because of its ultra-wide absorption spectrum from the ultraviolet to the terahertz band, ultrahigh carrier mobility and ultrafast photoreaction speed. In this study, a photothermal nano-device was made using graphene that was transferred to an electrode using an all-dry viscoelastic stamping method. The nano-device has the advantages of simplicity, high efficiency and instant measurement. This nano-device was used to measure the light absorption of graphene, and the calculated light absorption rate of graphene is basically consistent with previous research results. Experiments on irradiation at different wavelengths and thermal heating at different temperatures show that the nano-device has an excellent response to near-infrared and mid-infrared light. The conclusions provide an experimental basis for the research, design and fabrication of nano-devices, and this device can provide an effective method for detecting light and temperature in areas such as electronic components and solar cells.
