Unconventional magnetotransport fingerprints in the quantum Hall regime in chemically functionalized graphene

A work by the ICN2's Theoretical and Computational Nanoscience Group, led by the ICREA Research Prof Stephan Roche, describes in 2D Materials a new playground for tailoring the fundamental characteristics of the quantum Hall effect.

Tailoring the properties of Graphene and two-dimensional materials has been a topic of intensive research during the last few years. When experimentation is not possible simulation and theory become an essential tool. A work by the ICN2's Theoretical and Computational Nanoscience Group, led by the ICREA Research Prof Stephan Roche, describes in 2D Materials unconventional magnetotransport fingerprints in the quantum Hall regime in chemically functionalized graphene. The published results unveil a new playground for tailoring the fundamental characteristics of the quantum Hall effect. Nicolas Leconte was the first author of the study.

2D Materials is a young, multidisciplinary, electronic-only journal devoted to publishing fundamental and applied research covering all aspects of graphene and related two-dimensional materials. It usually complements its articles with a video where the authors of the work underline some of the main aspects of the study. Visit the magazine's website to learn more about the work and watch the presentation video shoot at ICN2.
