Single proton detector based on graphene on SiC

Acreo Swedish ICT engage in the fabrication of a  detector able to sense single protons using graphene on silicon carbide. Such a demonstration device can initiate a new application area that has the potential to develop very sensitive new devices for detecting ionizing particle irradiation on living cells.

Thin proton transmission detectors have previously been fabricated using silicon, however the exhibit too high noise  in order to enable sensing of single protons.

A new structure of graphene on silicon carbide is expected to realize a single proton detector with low noise. The proton produces a charge, and this will be detected using the graphene conductive layer on the silicon carbide.

Compared to silicon, is silicon carbide highly resistive to beam damage.

The project is funded with a grant from VSF - VERIFIERING FÖR SAMVERKAN, a program financed by VINNOVA through Uppsala University, Lund University, Linköping University and Karolinska Institutet to support joint projects between academia and the private, public or non-profit activities. With VFS, people have the opportunity to go from a collaboration idea to concrete test.


Start date: 1st Sept. 2014

Consortium: Lund University, Graphensic AB and Acreo Swedish ICT AB

Coordinator: Jan Pallon, Department Nuclear Physics, Lund University.


Based on this project, Graphensic AB, Acreo Swedish ICT AB and other two Swedish industrial partners are planning to apply for funding for a joint project to Vinnova Graphene SIP/SIO call. More info about the SIP Graphene can be found through ElektronikTidningen on 2014-09-15.
