The chip provides 27 graphene devices distributed in a grid pattern on the chip. The devices have interdigitated contacts on top of the graphene channel, which are optimal for sensing of gases and volatile compounds. All the devices have the same channel length (1mm), but 3 different widths (50µm, 100µm and 200µm). The interdigitated contacts have 3 different gaps (8µm, 15µm and 25µm). These different graphene channel dimensions allow investigation of geometry dependence on device properties, enabling immediate device optimization.\u003c\/p\u003e\n\u003ch3\u003eTypical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eGrowth method: CVD synthesis\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eGraphene transfer: Polymer assisted transfer\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSubstrate: Si\/SiO2\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSubstrate thickness: 675 μm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eResistivity of Si substrate: 1-10 Ω.cm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eGate oxide thickness: 90 nm\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMetallization: 50nm Au-based Contacts\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eChip dimensions: 10 mm x 10 mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNumber of GFETs per chip:  27\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eOptical Yield: ≥75\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAverage field-effect mobility: \u0026gt;1000 cm2\/V·s\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAverage Dirac point: \u0026lt;25 V\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAbsolute Maximum Ratings\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eMaximum gate-source voltage (back gating): ± 50V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMaximum temperature rating: 150 °C\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eMaximum drain-source current density: 10\u003csup\u003e7\u003c\/sup\u003eA.cm\u003csup\u003e-2\u003c\/sup\u003e\u003c\/span\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eQuality Control\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eAll our samples are subjected to a rigorous QC in order to ensure a high quality products.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eOptical microscopy inspection of all the devices\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRaman Spectroscopy of each fabrication batch\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eElectrical characterization via back gating of each fabrication batch\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eGraphene field-effect transistors (GFETs) have unprecedented sensitivity to the surrounding environment and is an ideal transducer for a variety of sensing applications.  Depending on the application, GFETs can be tuned to be sensitive only to the stimulus of interest and have shown breakthrough performance in areas such as graphene device research, quantum transport, gas sensors and chemical sensors.\u003c\/p\u003e\n\u003ch4\u003e\n\u003ca href=\"https:\/\/www.msesupplies.com\/\" rel=\"noopener\" target=\"_blank\"\u003eMSE Supplies\u003c\/a\u003e \u003cem\u003e\u003cstrong\u003e offers \u003c\/strong\u003e\u003c\/em\u003ehigh quality and best price on the market for GFETs products. \u003cem\u003e\u003cstrong\u003ePlease \u003ca rel=\"noopener\" href=\"https:\/\/www.msesupplies.com\/pages\/contact-us-page\" target=\"_blank\"\u003econtact us\u003c\/a\u003e for more information.\u003c\/strong\u003e\u003c\/em\u003e\n\u003c\/h4\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"MSE Supplies","offers":[{"title":"Pack of 4 Units","offer_id":40775037681722,"sku":"LS0065","price":936.95,"currency_code":"USD","in_stock":true},{"title":"1 Units","offer_id":40775037714490,"sku":"LS0066","price":252.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/20250210161812.jpg?v=1739175524","url":"https:\/\/www.msesupplies.com\/products\/mse-pro-gfet-graphene-field-effect-transistor-sensor-chip-optimal-for-gas-and-volatile-compound-detection","provider":"MSE Supplies","version":"1.0","type":"link"}
