Triangles of Quantum Dots Create Controllable Current Circulation

September 20, 2018

Chih-Chun Chien, Michael Scheibner, and collaborators have discovered a simple setup exploiting the quantum nature of electrons and triangular geometry to induce spontaneous current circulation between three quantum dots, in a new paper published in Europhysics Letters. In contrast to conventional designs which require external magnetic fields, their setup may lead to novel nanoscale magnetic switching or information storage devices.
