双层石墨烯NO2气敏特性
Gas sensitive properties of bilayer graphene for NO2
摘要
Abstract
Monolayer graphene and bilayer graphene are grown by chemical vapor deposition method and their gas sensing samples are prepared.The samples are characterized by Raman spectroscopy and optical microscopy.The gas-sensing responses of monolayer and bilayer graphene sensors for NO2 gas are tested.The results show that compared with monolayer graphene sensor,the gas desorption time of bilayer graphene sensor is shorter and the responsiveness is higher in low concentrations of NO2 gas volume fraction.The bilayer graphene response time increases nearly ten times and its desorption time shortens nearly four times at the order of 10-6 gas volume fraction.The detection Lower limit of bilayer graphene sensor also reaches 50 × 10-9.关键词
