31 May 2011 | | Abstract: | Topological insulators are insulating in the bulk but possess metallic
surface states protected by time-reversal symmetry. The existence of these
surface states has been confirmed by angle-resolved photoemission spectroscopy
(ARPES) measurements. Here, we report a detailed electronic transport study in
high quality Bi2Se3 topological insulator thin films contacted by
superconducting (In, Al and W) electrodes. The resistance of the film shows an
abrupt and significant upturn when the electrodes becomes superconducting. In
turn, the Bi2Se3 film weakens the superconductivity of the electrodes, reducing
both their transition temperatures and critical fields. A sensible
interpretation of these results is that the superconducting electrodes are
accessing the surface states and the experimental results are the consequence
of the interplay of the cooper pairs and the spin polarized current. | | Source: | arXiv, 1105.6174 | | Services: | Forum | Review | PDF | Favorites | |
