Superconducting phenomenon has been creating a splash with its diverse usages such as MRI and magnetic levitation train. However, it can only be operated under -240 celsius, so there were considerable limitations. The same phenomenon that can be operated above -200 celsius, called high-temperature superconducting phenomenon, was barely discovered in the 1980’s.
The 3D shape of electron alignment that can solve mysterious high-temperature superconducting phenomenon was discovered by a research team of ex-Postechians. The team found that charge density waves that were commonly thought to only exist in 2D can exist in 3D alignment under a strong magnetic field, using the world’s brightest X-ray from POSTECH’s 4th generation accelerator.
The result is taking center stage as a discovery of the fundamentals of high-temperature superconducting phenomenon. “3D characteristic of a high-temperature superconductor is an unprecedented discovery, and this will help understand the mechanics of the high-temperature superconductor,” said Dr. Lee Jun-Sik, the leader of the research team. "We will carry on our experiments to enlighten the undiscovered area of superconductors." said Dr. Jang Ho-young, the coauthor of the research. Dr. Jang and Dr. Lee are both SLAC research memers in Stanford University.
