The chip provides 31 graphene devices with a van der Pauw (vdP) geometry, distributed in 3 different sizes. 3 vdPs have a 2x2mm2 footprint, 14 vdPs have a 500x500µm2 footprint and 14 vdPs have a 125x125µm2 footprint. These devices have an optimized geometry for 4-probe measurements in a vdP configuration. These varying graphene device dimensions allow investigation of geometry dependence on device properties, enabling immediate optimization.\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\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\u003eChip dimensions: 10 mm x 10 mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e Number of GFETs per chip:  31\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: \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, chemical sensors and magnetic sensors.\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 GFETs 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":40775022575674,"sku":"LS0061","price":936.95,"currency_code":"USD","in_stock":true},{"title":"1 Units","offer_id":40775022608442,"sku":"LS0062","price":252.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/20250210160422.jpg?v=1739174675","url":"https:\/\/www.msesupplies.com\/products\/mse-pro-gfet-graphene-field-effect-transistor-chip-with-a-van-der-pauw-vdp-geometry-10mm-x-10mm","provider":"MSE Supplies","version":"1.0","type":"link"}
