Two Papers about CVD graphene published

Recently, two papers have been published by our group regarding the technology of chemical vapor deposited graphene.

The first paper titled “Self-organized growth of graphene nanomesh with increased gas sensitivity” was published in the August edition of the journal “Nanoscale”. The paper discusses the self-organized growth of graphene nanomeshes and their applicability as gas sensors. It was published as the result of a collaboration between the University of Siegen and Infineon Technologies AG, Regensburg, Germany: A bottom-up chemical vapor deposition (CVD) process for the growth of graphene nanomesh films is demonstrated. The process relies on silicon nanospheres to block nucleation sites for graphene CVD on copper substrates. This new method for nano-patterned graphene is scalable, inexpensive and can be carried out in standard semiconductor industry equipment. Furthermore, the substrates are reusable. The paper can be found here.

Focus on 2D materials

For two days, the University of Siegen was the national meeting place for experts from the field of innovative materials and technologies. Over 100 experts from academia, business and politics discussed the latest research findings.

Just an atom layer thin, yet also extremely robust and flexible – these are the properties of graphs and other “two-dimensional materials”. The high-tech substances could be used in a wide range of areas in the future: from sensors for smartphones, biomarkers in medical diagnostics and data communication with the highest transfer rates through to safety technology in cars. How the potential of 2D materials can be exploited was recently the subject of a two-day event at the University of Siegen.
