Researchers from Technical University of Denmark (DTU) synthesized a novel nano material with electrical and magnetic properties that is compatible with quantum electronics

A research led by Kasper Steen Pedersen, assistant professor at DTU Chemistry, synthesized Chromium-Chloride-Pyrazine, a nano material with electrical and magnetic properties. The material can be compatible with quantum computers and other applications in electronics. The layered material is a precursor for its 2D material. A material in 2D has a thickness of just a single molecule. Such 2D structure offers the material with different properties than its 3D version. In a 3D version, electrons are able to take any direction, whereas in 2D, the electrons are restricted to horizontal movement. Graphene is a 2D material that consists of carbon atoms in a lattice structure. The structure offers graphene its remarkable strength. Researchers around the world are focused on synthesizing other 2D materials, some of which may be candidates for quantum electronics applications.

However, the material developed at DTU is based on a different concept. Unlike graphene, which is inorganic, Chromium-Chloride-Pyrazine is an organic/inorganic hybrid material. The material’s hybrid property enables replacement of various building blocks in the material and thereby modifying its physical and chemical properties. Moreover, both electrical properties and magnetic properties in Chromium-Chloride-Pyrazine can be accurately designed. In conventional electronics, only the charge of the electrons is utilized. However, an electron’s spin, which is a quantum mechanical property, is used in spintronics. Such property in Chromium-Chloride-Pyrazine is useful in quantum computing applications. Moreover, the material may be applied in future superconductors, catalysts, batteries, fuel cells, and electronics in general. Although, no significant commercialization of 3D materials such as Chromium-Chloride-Pyrazine has started, the researchers stressed that the fundamental research on such a material synthesized from an entirely novel approach, generates several unanswered questions. For instance, the researchers are not yet able to determine the degree of stability of the material in various applications. The research was published in the journal Nature Chemistry on September 10, 2018.
