A team led by City College of New York physicist Lia Krusin-Elbaum is behind research that could open a breadth of new quantum device platforms for harnessing emergent topological states for nano-spintronics and fault-tolerant quantum computing.
The group of physicists and chemists has invented a new facile and powerful technique that uses ionic hydrogen to reduce charge carrier density in the bulk of three-dimensional (3D) topological insulators and magnets. The result is that robust non-dissipative surface or edge quantum conduction channels can be accessed for manipulation and control. Their research, "Topological surface currents accessed through reversible hydrogenation of the three-dimensional bulk," appears in the journal Nature Communications.
