Quantum Dots and Andreev Reflections in Graphene Quantum Dots and Andreev Reflections in Graphene

Preface By the end of my Master's thesis in University of Groningen in 2006, I was convinced that I wanted to do a PhD working on cold atoms. However, Marius Costache, who was at that moment a PhD student in Groningen, urged me to apply also to the quantum transport group (QT) in Delft. So I did. During my interview in Delft, QT people impressed me for being exceptionally smart and at the same ...

Giant Zero-Bias Conductance and Multiple Andreev Reflections in Carbon Nanotubes with Superconducting Contacts

Superconducting metal leads strongly modify the electronic conductance through carbon nanotubes. Depending on the nanotube transparency, which is controlled by the gate voltage, we observe a strong enhancement of the zero-bias conductance (way above the ballistic limit of 4e/h) or formation of a tunneling gap. Subgap structures corresponding to the Multiple Andreev Reflections are also found. A...

HREM Characterization of Interfaces in Thin MOCVD Superconducting Films

This paper is concerned with high-T, superconducting compounds produced by metal-organic chemical vapour deposition. The nanostructure of different types of interfaces yttria stabilized zirconia buffer / (l-102)-sapphire substrate, YBazCu307-, film / Y2O3 precipitates as well as YBa2Cu307-, film / (001)-NdGa03, -SrTiO3, and -MgO substrates has been investigated by high resolution electron micro...
