Scanning tunneling spectroscopy study of epitaxial graphene on superconducting rhenium

set to 1.8 V. These spectra are shown in Figure I. The same study has been done for Ptlr- Au tunneling junction and spectra were recorded in the 10 nA 100 nA range at a surface

The thickness dependence agrees with a proximity type model in which the film consists of a thin, non-superconducting, surface layer in contact with a remaining, bulk

The broad feature in the Raman spectrum around 1355 cm −1 can also be associated with peaks in the vDOS of the buffer layer that are due to flat phonon bands.. The phonon bands of

I(V) characteristics on temperature and magnetic field and from their reproducibi,lity we conclude that the double peak of procedure B cannot result from a gap anisntropy

Accordingly, since it has been argued recently 16 that feeding a growing current into a superconductor drives continuously the superconducting phase to the normal one, this article

Pippard 8–10 carried out the first measurements of electromagnetic energy absorption at a frequency ω ≈ 10GHz in superconducting Sn, containing impurities, and interpreted his

to an external magnetic field. Semi-classical analysis is introduced in order to give very accurate asymptotic behavior of the supercooling field as the.. thickness
