From Cooper pair splitting to the non-local spectroscopy of a Shiba state
Zoltán Scherübl, Gergő Fülöp, Jörg Gramich +4
Cooper pair splitting (CPS) is a way to create spatially separated, entangled electron pairs. To this day, CPS is often identified in experiments as a spatial current correlation.…
Large spatial extension of the zero-energy Yu-Shiba-Rusinov state in magnetic field
Zoltán Scherübl, Gergő Fülöp, Cătălin Paşcu Moca +8
Various promising qubit concepts have been put forward recently based on engineered superconductor (SC) subgap states like Andreev bound states, Majorana zero modes or the Yu-Shiba…
Non-equilibrium properties of graphene probed by superconducting tunnel spectroscopy
Simon Zihlmann, Péter Makk, Sebastián Castilla +6
We report on non-equilibrium properties of graphene probed by superconducting tunnel spectroscopy. A hexagonal boron nitride (hBN) tunnel barrier in combination with a superconduct…
Andreev bound states probed in three-terminal quantum dots
J. Gramich, A. Baumgartner, C. Schönenberger
We demonstrate several new electron transport phenomena mediated by Andreev bound states (ABSs) that form on three-terminal carbon nanotube (CNT) QDs, with one superconducting (S)…
Subgap resonant quasiparticle transport in normal-superconductor quantum dot devices
J. Gramich, A. Baumgartner, C. Schönenberger
We report thermally activated transport resonances for biases below the superconducting energy gap in a carbon nanotube (CNT) quantum dot (QD) device with a superconducting Pb and…
Resonant and inelastic Andreev tunneling observed on a carbon nanotube quantum dot
J. Gramich, A. Baumgartner, C. Schönenberger
We report the observation of two fundamental sub-gap transport processes through a quantum dot (QD) with a superconducting contact. The device consists of a carbon nanotube contact…
Fork stamping of pristine carbon nanotubes onto ferromagnetic contacts for spin-valve devices
J. Gramich, A. Baumgartner, M. Muoth +2
We present a fabrication scheme called 'fork stamping' optimized for the dry transfer of individual pristine carbon nanotubes (CNTs) onto ferromagnetic contact electrodes fabricate…
Carbon nanotube quantum dots on hexagonal boron nitride
A. Baumgartner, G. Abulizi, K. Watanabe +3
We report the fabrication details and low-temperature characteristics of the first carbon nanotube (CNT) quantum dots on flakes of hexagonal boron nitride (hBN) as substrate. We de…
Fabrication and characterisation of nanospintronic devices
J. Samm, J. Gramich, A. Baumgartner +2
We report an improved fabrication scheme for carbon based nanospintronic devices and demonstrate the necessity for a careful data analysis to investigate the fundamental physical m…
Experimental verification of contact-size estimates in point-contact spectroscopy on superconductor/ferromagnet heterocontacts
J. Gramich, P. Brenner, C. Sürgers +2
Nanostructured superconductor/ferromagnet heterocontacts are studied in the different transport regimes of point-contact spectroscopy. Direct measurements of the nanocontact size b…
