Three-dimensional quantum Hall experiment featured at national science exhibition
A public exhibition in Beijing featured the quantum transport experiment by researchers from SUSTech, the University of Science and Technology of China and their collaborators.
The national exhibition of science and technology achievements from China’s 13th Five-Year Plan opened at the Beijing Exhibition Center on 21 October. The University of Science and Technology of China (USTC) listed the observation of the three-dimensional quantum Hall effect in bulk ZrTe₅ among the physics results on display.
The work brought together Liyuan Zhang’s group at SUSTech, Zhenhua Qiao’s group at USTC and other collaborators. They found signatures of the quantum Hall effect, familiar from two-dimensional electron systems, in millimetre-scale three-dimensional crystals. The exhibition was open to the public through 27 October.
