Research Progress of the Graphene-Based Resonator

对石墨烯谐振器的研究进展进行了综述,包括谐振器的实验、理论建模研究、应用及其发展前景,并指出了获得高性能谐振器所要考虑的几个影响因素。从中可以看出石墨烯的尺寸、门电压的大小、温度的高低和初始张力的大小等因素对谐振器性能的影响,从而获得尽量高的品质因数。石墨烯谐振器在纳米级别应用如质量传感器、加速度计、应变传感器和热传感器都有所研究,而且所获得的性能比碳纳米管高很多。目前,石墨烯谐振器在这些领域的应用只停留在理论阶段,缺少相应的实验研究,实现其商业化还需要一段时间,但石墨烯的制备已达到一个非常高的水平,石墨烯谐振器将应用于越来越多的领域。

The research progresses for graphene-based resonators are reviewed, including the ex- periment, theoretical modeling research, application and development prospect, etc. Several influence factors for the high-perfor-mance resonator are pointed out. The effects of the factors such as the dimension of the graphene, gate voltage, temperature and initial tension on the performances of the resonator are found, and the quality factor as high as possible can be obtained. The nanoscale applications of graphene-based resonators, such as mass sensor, accelerometer, strain sensor and thermal sensor are introduced, and the obtained performances are much higher than those of the carbon nanotube-based resonators. At present, the applications of the graphenebased resonators in these fields are mainly theoretical. It will take some time for sensors to achieve commercialization for lacking corresponding experimental studies, but the preparation of the graphene has reached a very high level. The graphenebased resonarors will be applied to more and more fields.
