Structural and functional characteristics of the ionic liquid – graphene interface KU Leuven
Electrochemical energy systems are key for developing sustainable and reliable energy supply to meet the future energy demands. Volatility and flammable nature of conventional electrolytes, however, limit their safe usage in energy applications. Ionic liquids (ILs), a new class of electrolytes show remarkable chemical and thermal stability. Graphene, a single layer of carbon atoms in a two-dimensional hexagonal lattice, showcases key ...
Modification of 2D materials like graphene and MoS2 by molecular self-assembly: structure and function. KU Leuven
2Dfun aims at establishing 2D layers and heterogeneous layer stacks as basic building blocks of, and demonstrate them in functional devices. To this end, 2Dfun will develop growth processes for 2D transition metal dichalcogenides (MX2) on graphene (with graphene coming from external resources within the Flagship) as well as high-k dielectric layers on MX2. Almost all work reported in literature in this area is based on natural MX2 material ...

Growth and transfer of high quality graphene for advanced photonics applications. KU Leuven
Graphene, the wonder material, started 2-dimensional (2D) material interest in 2004. In that year, Geim and Novoselov were the first to isolate and characterize a single graphene sheet. Graphene itself is an atomically thin sheet of sp2-hybridized carbon atoms, which are organized in a honeycomb lattice. This crystalline structure gives rise to extraordinary mechanical properties, finding applications in the field of composites, medicine and ...
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.
In this Ph.D thesis ...
Graphene as a sensing platform for the adsorption and desorption kinetics of gas molecules on few-atom clusters KU Leuven
Few-atom clusters show great promise as catalysts for a number of industrially relevant chemical reactions due to their high reactivity and size-dependent physical properties. To fully exploit their catalytic properties, a detailed understanding of the adsorption and desorption reaction of gas molecules on the clusters is of paramount importance. In this regard, graphene offers interesting possibilities. Graphene, a two-dimensional 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 ...
