New Publication on High Sensitivity UV Detection Using Graphene Silicon Photodiodes
AMO GmbH is pleased to have contributed to a new scientific publication on high sensitivity graphene silicon Schottky photodiodes. The paper entitled “High UV sensitivity in graphene silicon Schottky photodiodes in industry standard packaging” has been published Open Access in the journal Springer Nature npj Applied Materials & Applications.
The first authors of the publication are Ardeshir Esteki and Christoph Gebauer, who contributed equally to the reported results. Additional co authors include Jülide Avci, Heinrich Gottlob and Max Lemme.
The study demonstrates for the first time that graphene silicon Schottky photodiodes can be successfully integrated into industry standard semiconductor packaging. This represents an important step toward the industrial applicability of these devices. By exploiting graphene’s high carrier mobility and broad optical transparency, the developed photodiodes achieve exceptional sensitivity in the ultraviolet spectral range.
Measurement results show that the responsivity of the packaged devices clearly exceeds that of commercial silicon and gallium phosphide photodetectors. At the same time, their performance approaches the level of silicon carbide based detectors. Comprehensive reliability tests further confirm stable dark current and photocurrent characteristics over more than 900 hours under industrial lifetime stress conditions.
These findings highlight the strong potential of graphene silicon Schottky photodiodes as a promising alternative to conventional UV photodiodes. They open new perspectives for future industrial applications including process monitoring, environmental sensing and optical measurement technologies.
The work was carried out in close collaboration with the Chair of Electronic Devices at RWTH Aachen University, Vishay Semiconductor GmbH in Heilbronn and AMO GmbH.
The research was funded by the European Union’s Horizon 2020 Research and Innovation Program within the Graphene Flagship Core 3, by the Federal Ministry for Research, Technology and Space, and by the Deutsche Forschungsgemeinschaft.
