| Аннотация |
Superconducting proximity devices using low-dimensional semiconducting elements enable a ballistic regime in the proximity transport. The use of topological insulators in such devices is considered promising owing to the peculiar transport properties these materials offer, as well
the hope of inducing topological superconductivity and Majorana phenomena via proximity
effects. Here we demonstrate the fabrication and superconducting properties of proximity
Josephson devices integrating nanocrystals single of Bi2Te2.3Se0.7 with a thickness of a few
unit cells. Single junctions display typical characteristics of planar Josephson devices; junctions integrating two nanocrystals behave as nanodimensional superconducting quantum
interference devices. A peculiar temperature and magnetic field evolution of the Josephson
current along with the observed excess current effect point towards the ballistic proximity
regime of topological channels. This suggests the proposed devices are promising for testing
topological superconducting phenomena in two-dimensions. |
