The studies were motivated by the fact that the low-frequency noise can be up-converted by device nonlinearity and contribute to the phase noise of the system. Similarly, the sensor sensitivity is often limited by the electronic low-frequency noise. Therefore, noise is usually considered as one of the main limiting factors for the device or overall system operation. However, the electronic noise spectrum itself can be used as a sensing parameter increasing the sensor sensitivity and selectivity. Here, we show that vapors of different chemicals produce distinguishably different effects on the low-frequency noise spectra of the graphene-on-Si transistor. Our study showed that some gases change the electrical resistance of pristine graphene devices without changing their low-frequency noise spectra while other gases modify the noise spectra by inducing Lorentzian components with distinctive features. The characteristic corner frequency fC of the Lorentzian noise bulges in graphene devices is different for different chemicals and varies from fC=10 - 20 Hz for tetrahydrofuran to fC=1300 - 1600 Hz for chloroform. We tested the selected set of chemicals vapors on different graphene device samples and alternated different vapors for the same samples. The obtained results indicate that 1/f noise in combination with other sensing parameters can allow one to achieve the selective gas sensing with a single pristine graphene transistor. Our method of gas sensing with graphene does not require graphene surface functionalization or fabrication of an array of the devices with each tuned to a certain chemical. The observation of the Lorentzian components in the vapor-exposed graphene can also help in developing an accurate theoretical description of the noise mechanism in graphene.","PeriodicalId":6402,"journal":{"name":"2012 IEEE Silicon Nanoelectronics Workshop (SNW)","volume":"54 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2012-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83852206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the use of a boron nitride layer between the graphene and the silicon dioxide substrate has shown enhanced mobilities due to displacing the disorder charge, typical on the oxide, further from the graphene material. On the other hand, like the oxide, boron nitride has polar optical modes which can interact with the carriers in graphene to lower their mobility. We have used an ensemble Monte Carlo technique to study the transport in graphene on a boron nitride layer. Scattering by the intrinsic phonons of graphene, as well as by the flexural modes of the rippled layer, and the remote polar mode of boron nitride has been included. The flexural modes are described by the model of Castro et al. While the EMC uses the simple Dirac band structure, coupling constants for the intrinsic phonon modes are taken by fitting to scattering rates determined from first-principles calculations. We find that, at low temperatures, the mobility is dominated primarily by the intrinsic graphene phonons and the flexural modes. This arises as the interfacial polar mode of boron nitride lies at an energy of 200 meV, which is largely too high to interact well with the majority of the carriers in graphene. On the other hand, at room temperature, the mobility begins to be dominated by the remote polar mode of the boron nitride. Nevertheless, the prospects of reaching a high velocity, needed for device performance particularly at microwave frequencies, remains very good.","PeriodicalId":6402,"journal":{"name":"2012 IEEE Silicon Nanoelectronics Workshop (SNW)","volume":"88 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2012-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86338211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
