Purpose and goal

The goal of this project is to develop a low cost graphene device processing technology for two main applications: 1) Graphene chemical sensors to detect drugs (cocaine and amphetamine) for cost effective onsite crime scene analysis , 2) Plasmonic graphene-based infrared (IR) detectors [wavelength range 2-10 µm] to sense CO2 and/or alcohol in an industrial setting and comparing its performance with existing detectors available in the market.

Expected results and effects

The project will not only focus on the graphene sensor/detector design, fabrication and characterization aspects, but also an investigation of yield, cost and product potential. It will address the processing issues of the graphene structures to achieve the desired selectivity of chemical sensors, and will also help us know how much enhancement of IR signal responsivity can be achieved.

Planned approach and implementation

-State-of-the-art survey, provide short term and long-term visions of the project, set the specifications of the graphene-based sensors/IR detectors (SenseAir AB, Polismyndigheten/Nationellt Forensiskt Centrum).[WP 1&2] -Design of graphene structures based on the given specs.(KTH), developing a process technology for their fabrication,and practical implementation (RISE Acreo AB). [WP 3&4] -Characterization of the sensors (Pamitus AB), testing of samples, data analysis and validation (Pamitus AB, RISE Acreo AB, Nationellt Forensiskt Centrum). [WP 5]
