The chip is designed for measurements in liquid medium. The new version provides 12 graphene devices, with encapsulation on the metal pads to avoid degradation and reduce leakage currents, and the probe pads located near the periphery of the chip. It also includes a non-encapsulated electrode at the center of the chip, which allows liquid gating without the need of an external gate electrode.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cstrong\u003eTypical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\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\u003eChip dimensions: 10 mm x 10 mm\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\u003cspan\u003eGate oxide thickness: 90 nm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMetallization: 50nm Au-based Contacts\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e Encapsulation: 50 nm Al2O3\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\u003e Number of GFETs per chip:  12\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOptical Yield: ≥75\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAverage field-effect mobility (back gating): \u0026gt;1000 cm2\/V.s\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAverage Dirac point (back gating): \u0026lt;25 V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eAverage Dirac point (liquid gating): \u0026lt;1 V\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\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 (liquid gating in PBS): ± 2V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e Maximum 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: 107A.cm-2\u003c\/span\u003e\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\u003eElectrical characterisation (back gating and liquid gating) of each fabrication batch\u003c\/li\u003e\n\u003cli\u003eAFM of each fabrication batch\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 photosensing, magnetic sensing and biosensing.\u003c\/p\u003e\n\u003ch4\u003e\n\u003ca rel=\"noopener\" href=\"https:\/\/www.msesupplies.com\/\" 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 our graphene products. \u003cem\u003e\u003cstrong\u003ePlease \u003ca href=\"https:\/\/www.msesupplies.com\/pages\/contact-us-page\" rel=\"noopener\" 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":40775014645818,"sku":"LS0059","price":1429.95,"currency_code":"USD","in_stock":true},{"title":"1 Units","offer_id":40775014678586,"sku":"LS0060","price":404.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/S20_1_720x_af5c2d9a-764f-4fe3-ae3e-d282fad97635.webp?v=1739171059","url":"https:\/\/www.msesupplies.com\/en-de\/products\/mse-pro-gfet-graphene-field-effect-transistor-chip-for-liquid-sensors-10mm-x-10mm","provider":"MSE Supplies","version":"1.0","type":"link"}
