Researchers have discovered that thin films of elemental bismuth exhibit the so-called non-linear Hall effect, which could be applied in technologies for the controlled use of terahertz high-frequency ...

Researchers from the University of Salerno in Italy and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have found that thin layers of pure bismuth display the non-linear Hall effect, offering ...

Particularly: the quantum effect is observed at room temperature. The thin-layer films can be applied even on plastic substrates and could therefore be suitable for modern high-frequency technology ...
