Important results from the project
1) The partners have exchanged knowledge during the project through discussions of design and results, and through the writing of a follow-up project proposal. 2) KTH has developed a new process for the fabrication of suspended silicon waveguides onto which graphene detectors can be integrated. 3) The performance of the suspended silicon waveguides has been evaluated. 4) The commercial potential has been evaluated.
Expected long term effects
Through our work in this pre-study project, the partners have been able to submit a competitive proposal called ´Waveguide-Integrated Graphene Based Mid-Infrared Detectors for Optical Gas Sensor Chips´ to the FlagERA Graphene call, with two new international partners. Thereby the partners have already expanded their international network in the graphene community.
Approach and implementation
The project plan consisted of two work packages: WP1 Knowledge transfer and WP2 mid-IR detector prototype. WP1 was executed mostly through discussions on the requirements for a IR detectors in gas sensor chips. These results guided the prototype design, and formed the core of the follow up application to FlagERA Graphene. WP2 was executed through common design meetings, by fabrication of the prototype in the KTH clean-room, and evaluation at the KTH characterization laboratories. This method of operation worked well.
