Graphene has been of immense interest for its interesting electronic properties, such as being a zero-band gap semiconductor. However, to be able to usefully employ graphene for electronics and electronic-transduction system sensors and biosensors, one needs to open this band gap. This proofs to be challenging on reproducible, scalable way. There are other 2D monoelemental materials that exhibit useful band gap and which can be used for field effect transistor- (FET-) based sensing and biosensing. Here we discuss trends in the development of FET-based sensors utilizing 2D phosphorene, arsenene, antimonene, silicene, and germanene.

基于单元素2D材料的场效应晶体管，用于传感和生物传感：磷，锑，砷，硅和锗烯超越了石墨烯

石墨烯因其令人感兴趣的电子特性（例如作为零带隙半导体）而备受关注。然而，为了能够有效地将石墨烯用于电子和电子转导系统传感器以及生物传感器，需要打开该带隙。这证明在可重现，可伸缩的方式上具有挑战性。还有其他2D单元素材料表现出有用的带隙，可用于基于场效应晶体管（FET）的传感和生物传感。在这里，我们讨论了利用2D磷，砷，锑，硅和锗烯的基于FET的传感器的发展趋势。
