Enhanced pinning and proliferation of matching effects in a superconducting film with a Penrose array of magnetic dots
A. V. Silhanek, W. Gillijns, V. V. Moshchalkov +3
The vortex dynamics in superconducting films deposited on top of a five-fold Penrose array of magnetic dots is studied by means of transport measurements. We show that in the low p…
Transport spectroscopy of a single dopant in a gated silicon nanowire
H. Sellier, G. P. Lansbergen, J. Caro +5
We report on spectroscopy of a single dopant atom in silicon by resonant tunneling between source and drain of a gated nanowire etched from silicon on insulator. The electronic sta…
Charge Transport Properties of a Metal-free Phthalocyanine Discotic Liquid Crystal
C. Deibel, D. Janssen, P. Heremans +4
Discotic liquid crystals can self-align to form one-dimensional semiconducting wires, many tens of microns long. In this letter, we describe the preparation of semiconducting films…
Zero-bias spin separation
Sergey D. Ganichev, Vasily V. Bel'kov, Sergey A. Tarasenko +12
Spin-orbit coupling provides a versatile tool to generate and to manipulate the spin degree of freedom in low-dimensional semiconductor structures. The spin Hall effect, where an e…
ENOBIO - First tests of a dry electrophysiology electrode using carbon nanotubes
Giulio Ruffini, Stephen Dunne, Esteve Farres +7
We describe the development and first tests of Enobio, a dry electrode sensor concept for biopotential applications. In the proposed electrodes, the tip of the electrode is covered…
Sub-threshold channels at the edges of nanoscale triple-gate silicon transistors
H. Sellier, G. P. Lansbergen, J. Caro +5
We investigate by low-temperature transport experiments the sub-threshold behavior of triple-gate silicon field-effect transistors. These three-dimensional nano-scale devices consi…
