Research Group: Results of the experiment
The research group was the first in the world to determine the atomic arrangement of the “carbon atomic layer material graphene and calcium two-dimensional compound” that exhibits superconductivity.
Solved by using total reflection high-speed positron diffraction method (hereinafter referred to as TRHEPD method).
In addition, it was proved through experiments that this atomic arrangement “shows the superconductivity * 2 phenomenon where the electrical resistance is zero”.
Application fields:
This time, we have clarified the atomic arrangement of a new compound using graphene.
In the future, this will pave the way for the development of materials such as “Ultra-high-speed information processing nanodevices with zero energy loss”.
This research result was published on October 25, 2019 (local time) in the online version of Carbon.
