Problems solved by technology

However, the superconducting layer in the material they cleaved was severely damaged by external force, showing a wavy appearance.
The reason is that the superconducting layer and the transition layer are torn apart directly by external force, and the bending radius of the superconducting layer at the split point is very small, which is lower than the critical bending radius that the superconducting layer can withstand, resulting in the loss of the transmission ability of the superconducting current
