Graphene quantum dots probed by scanning tunneling spectroscopy and transport spectroscopy after local anodic oxidation

15 May 2015 Morgenstern Markus Freitag Nils Vaid Aviral Pratzer Marco Liebmann Marcus

Graphene quantum dots are considered as promising alternatives to quantum dots in III-V semiconductors, e.g., for the use as spin qubits due to their consistency made of light atoms including spin-free nuclei which both imply relatively long spin decoherene times. However, this potential has not been realized in experiments so far, most likely, due to a missing control of the edge configurations of the quantum dots... (read more)
