'Quantum Hall-like effect' found in a bulk material without an applied magnetic field

A team of scientists from Princeton University has found that the so called quantum Hall effect, which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields can occur in a bulk crystal of bismuth-antimony without any external magnetic field being present.
This work, could lead to advances in new kinds of fast computing devices, of potential use in future electronic technologies.

In "B" and "C", either the electric current or the magnetic field is reversed, causing the polarization to reverse. Reversing both current and magnetic field (drawing "D") causes the Hall element to again assume a negative charge at the upper edge. clipped from en.wikipedia.org Quantum Hall effect The quantum Hall effect (or integer quantum Hall effect) is a quantum-mechanical version of the Hall effect, observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields,
