Shenzhen awards first prize to the three-dimensional quantum Hall experiment
The group's experimental observation of the three-dimensional quantum Hall effect received first prize in Shenzhen's 2022 Natural Science Awards.
The Shenzhen municipal gazette reported on 21 June that the city had approved its 2022 science and technology awards on 10 June. The natural science award recognised Liyuan Zhang's group for its experimental observation of the three-dimensional quantum Hall effect.
The researchers studied bulk ZrTe₅ crystals at low temperatures in a magnetic field. When carriers occupied only the lowest Landau level, the Hall resistance showed a plateau and the longitudinal resistance fell close to zero.
