Honda: Technology for synthesizing nano-materials

2021: Announcement of technology for synthesizing nano-materials

On December 27, 2021, the company Honda announced that scientists Honda Research Institute located in (USA Honda Research Institute USA, Inc. - HRI-US), using the synthesis method, created atomically thin "nano-tapes." This achievement may affect the future development of quantum electronic engineers physics, a field of physics that studies the influence of quantum mechanics on the behavior of electrons in matter.

As reported, the HRI-US synthesis of ultra-thin two-dimensional material created from a single or double layer of atoms demonstrated the ability to control its width within 10 nanometers (10-9 meters). This means that quantum transfer can occur at higher temperatures than those required for materials created by existing methods. A team of scientists, along with collaborators from the universities of Columbia and Rice, as well as from the national laboratory of Ok Ridge, wrote a paper about this that was published in Science Advances. The article is also available on the website: science.org.

Honda Research Institute has developed technology for synthesizing nano-materials

Synthesis technology can allow the creation of two-dimensional materials that will allow the use of quantum technologies, in particular, quantum calculations and probing, at temperatures higher than those necessary for the materials used.

Modern materials are manufactured mainly by nanolithography - it allows printing or etching nanometer-scale structures. However, HRI-US scientists have developed a method for controlled cultivation of materials using nickel nanoparticles, which can allow controlling the width of two-dimensional materials such as molybdenum disulfide. In other words, it is possible to make the width much narrower than in cases where the synthesis method existing in December 2021 is applied. Narrow (about 7-8 nanometers) two-dimensional materials grown by HRI-US scientists show quantum electron transfer, known as Coulomb blockade oscillation, at temperatures of about 60 K (or -213 ° C), which is about 15 times higher than materials synthesized by conventional methods (4 K or -269 ° C). This opens the way to the creation of more energy-efficient quantum devices.

Our growing technology introduces width as an additional degree of freedom in atomically thin laminates, revealing the behavior of electrons in them. We see the possibility of application in high-speed electronics with low power consumption, spintronics, quantum probing, quantum and neuromorphic calculations. told Avetik Harutyunyan, Senior Fellow at HRI-US and co-author of an article in the journal Science Advances

We managed to achieve control of nano-tape MoS2 with a scale of atoms using nickel nanoparticles, which ensures the growth of nano-fiber by vapor-liquid-solid (VLS). We want to manage the edge structures of nano-tapes in another way to change their electronic properties. narrated by Dr. Xufang Li, Senior Fellow at HRI-US and lead author of the paper

Research on the properties of materials synthesized in HRI-US was supported by scientists from two universities and a national laboratory:

• Dr. Baichang Li, Dr. Yang Liu, and Professor James Hoon of the Department of Mechanical Engineering and the Center for Materials and Engineering Research (MRSEC) of Columbia University studied the electronic properties of the material.
• Dr. Jincheng Lay, Dr. Ksenia V. Bets and Professor Boris I. Jacobson of the Department of Materials Science and Nanoengineering, Rice University, conducted theoretical studies on material growth.
• Dr. Syahan Sang and Dr. Raymond R. Junocic of the Center for Nanophasic Materials Science of the Okridge National Laboratory determined the characteristics of the material with atomic resolution.
• Emmanuel Okogbu, participated in the synthesis of materials, working as an intern at the Honda Research Institute in the United States.
