A new method for the functionalization of graphene
International research team to modify the properties of graphene for its use in electronics
INRS
Graphene has outstanding physical, optical and mechanical properties. For instance, it is commonly used in the manufacture of transparent touch screens, in aerospace, and in biomedicine. This material, however, has limited use in electronics.
"No other material has properties similar to graphene, yet unlike semiconductors used in electronics, it lacks a band gap. In electronics, this gap is a space in which there are no energy levels that can be occupied by electrons. Yet it is essential for interacting with light," explains Professor Federico Rosei of INRS's Énergie Matériaux Télécommunications Research Centre.
"The multidisciplinary group of researchers from Canada, China, Denmark, France and the United Kingdom succeeded in modifying graphene so as to create a band gap. Current research is rather fundamental but could have repercussions over the next few years in optoelectronics, such as in the fabrication of photodetectors or in the field of solar energy. These include the manufacture of high-performance photovoltaic cells for converting solar energy into electricity, or the field of nanoelectronics, for the extreme miniaturisation of devices," emphasizes Professor Rosei.
This breakthrough is complementary to the results published in Nature Materials, in May 2020, by an Italian-Canadian team of researchers under the supervision of Professor Rosei.
