Tuning graphene into a spin active material: Exploiting its size-specific interaction with metal clusters KU Leuven
The success of semiconductor industry relies on the continuous improvement of the performances of integrated circuits (IC). So far, this has been achieved by reducing the size of the basic building block of these circuits, the metal-oxide-semiconductor field effect transistor (MOSFET). The downscaling of MOSFET’s has been realized by introducing new materials, like high-k dielectric/metal gate stacks and high-mobility semiconductors (Ge, ...
Modeling of Graphene for Interconnect Applications KU Leuven
With the reduction of the interconnect dimensions and the increased impact of process variations and process induced damage on the circuit performance, the standard Cu/Low-k damascene interconnects are now reaching their application limits. The increase in Cu resistivity with scaling and the enhanced reliability concerns at smaller dimensions are the main drivers towards replacing Cu with an alternative material.

Locally probing the magneto-structure of adatoms on graphene using radioions KU Leuven
Scientific state of the art
Solid state physics in reduced dimensionality is, more than a trend, a truly new working ground for contemporary research. The recent advent of nanoscience and nanotechnology (3-dimensional towards 1-dimensional and 0-dimensional) is a clear manifestation of that; graphene (and related 2-dimensional materials) is probably the richest and most recent one [1-5]. In fact, low dimensionality in ...
Graphene-Metal Contact Engineering and Graphene Interconnects KU Leuven
Graphene, an sp2-bonded carbon sheet of one atom thickness, is extensively studied as a very promising material for post-Si electronics. Among other challenges, the issue of contacting graphene is attracting more and more attention. The effect of the metal contacts on graphene and the contact resistance (Rc) values measured are matters of concern not only for graphene device performance but also of major relevance for hybrid graphene/metal ...

Functionalization of Graphene with Physisorbed Self-assembled Networks for Electronic Applications KU Leuven
Graphene is a promising material for future electronic applications. However, a prerequisite for the use of graphene in several electronic applications is the controlled and reproducible modification of its electronic and chemical properties. Among the different strategies for surface functionalization, physisorption of molecular adsorbates has as significant advance that it does not result in degradation of the charge carrier mobility. ...
