Graphene systems are the future of electronics and spintronics

Evgeny Tretyakov, Doctor of Chemical Sciences and Deputy Director of the Vorozhtsov Novosibirsk Institute of Organic Chemistry, presented a report at the 14th International Forum on Strategic Technology (IFOST 2019). It was dedicated to the production of graphene and graphene-like materials with desired properties, and also the application of research results in electronics and spintronics.

The IFOST forum, currently being held at TPU, is one of the largest events for research engineers around the world. The forum has been held since 2006. This year, it brought together more than 200 participants from Mongolia, China, Russia, Germany, France, Pakistan, Brazil, Uzbekistan, Tajikistan, and Kazakhstan. The forum program includes discussions of new innovative technologies and engineering solutions in various scientific domains.

Evgeny Tretyakov, Doctor of Chemical Sciences, presented the report “Carbon Graphene and Metal-Radical Graphene-like Magnets”. Nowadays, the graphene study is a very topical research area.

“Every day, about 100 scientific papers on graphene studies are published. This amount of information is difficult to consider. Nevertheless, within this domain, there are areas that need fundamental research ”,

— Evgeny Tretyakov admits.

His research deals with synthesizing graphene and graphene-like materials ‘from bottom to top’, i.e. creating a graphene fragment from individual molecules in solution. As a result, we obtain materials, which structure contains corner atoms of carbon or more complex structural formations, consisting of manganese ions and stable organic radicals.

In the future, such a material can be applied in electronics and spintronics. However, graphene structures still require extensive fundamental research. The main goals are to obtain graphene material with specified magnetic properties and conductivity.

“Within the framework of the forum, there were reports referring to the fact that the materials for the future electronics and spintronics should be graphene structures close to the 5-nanometer range,”

— Evgeny Tretyakov says.

Also, scientists plan to obtain synthesis of directed certain systems, including high-spin compounds. In these studies, the laboratory of Yevgeny Tretyakov collaborates with the Pavel Postnikov research team from Tomsk Polytechnic University.
