TOPOLOGICAL MATERIALS

Materials with topologically protected conducting or superconducting surface states are predicted to exhibit many unusual phenomena.

These phenomena include:

  • dissipationless transport along the edges of 2D structures
  • quantized anomalous hall conductance and inverse spin galvanic effect
  • exotic signatures of fundamental phenomena such as the Witten effect, wormholes and image magnetic monopoles
  • ability to host Majorana fermions, a new type of electronic particle that uniquely retains a quantum mechanical memory of its history – a property unlike any known today. 

SBQMI researchers are discovering how to exploit these phenomena to:

  • transform graphene into a 2D topological insulator,
  • understand the connection between bulk properties and the protected surface state in 3D topological material and which may form topological insulators
  • launch a new effort to investigate Marjorana fermions in networks of semi-conductor quantum wires.
