[Thesis]

Development and understanding of isotropic Silicon etching processes selectively to SiGe material for sub 10nm CMOS applications.

Offer N°: SL-DRT-16-0286

Start date: 1 Oct 2016

The most advanced CMOS technologies (beyond 10nm) call upon innovative architectures where new material integration as heteroepitaxy SiGe layers on Si becomes inevitable cause of its advantageous mobility properties for the charge carriers. SiGe epilayers used in particular for the conductive channel of the transistor are necessarily obtained by the selective removal of Si compared with SiGe.



[Thesis]

Interaction effects on topological properties of multiterminal Josephson junctions

Offer N°: SL-DSM-16-0253

Start date: 1 Sep 2016

There is currently an active search for new phases of matter that admit topologically protected edge states. A promising route to realize them consists in combining conventional materials into appropriate heterostructures. Multiterminal Josephson junctions between conventional superconductors may be considered as topological materials themselves. As an example, 4-terminal junctions can accommodate topologically protected zero-energy bound states, which form so-called Weyl singularities.



[Thesis]

Helical superconductivity and the anomalous Josephson effect

Offer N°: SL-DSM-16-0265

Start date: 1 Oct 2016

The interplay of spin-orbit coupling and the Zeeman effect due to a magnetic field plays an important role in the realization of so-called topological superconductivity. The aim of the proposed research is to study this interplay in novel materials such as transition metal dichalcogenide monolayers – twodimensional systems similar to graphene, but with two different atoms in the unit cell and having a strong spin-orbit coupling that is not of the Rashba type.



[Thesis]

Shiba states in superconducting graphene

Offer N°: SL-DSM-16-0307

Start date: 1 Sep 2016

Graphene, a monolayer of carbon atoms organized on a honeycomb lattice, displays outstanding electronic properties due to a linear dispersion of its electronic states close to the Fermi level. We grew graphene on top of Rhenium, a superconducting metal. Graphene becomes thus superconducting by proximity effect. The project consists in studying localized magnetic states (Shiba states) in superconducting graphene by tunnelling microscopy and spectroscopy (STM).
