Developing novel methodologies for the nano-optical characterization of 2D materials KU Leuven
Traditional optical spectroscopies are unparalleled analytical tools in science. However, a fundamental physical barrier known as the diffraction limit prevents them from accessing length scales beneath 200 nanometres. This is especially problematic for the family of 2D materials, such as graphene and the transition metal dichalcogenides (TMDs), which hold promise for cheap, next-generation LEDs, photovoltaic cells and photodetectors, amongst ...
PHD researcher on structure of 2Dsemiconductor-dielectrics interfaces. KU Leuven
As the academy found the abundant nature of graphene, a two-dimensional material which draws a lot of attention. After decades of research, it was found that the interesting nature of layered materials with strong in-plane bonding and weak out-of-plane interactions could possibly leads the semiconductor device application into a new era. However the electrical properties of graphene is not suitable to be a channel in a metal-oxide ...

Engineering Two-Dimensional Materials and Their Surroundings for Improved Electrical Performance KU Leuven
2D materials, promising excellent electrostatic control, are being investigated to replace Si in highly scaled field-effect transistors (FETs). Performance of these 2D FETs is determined in large part by the transport properties of the 2D material. While predictions for free-standing 2D materials show high electron mobilities (>200cm2/Vs), the mobilities in practice turn out much lower (<30 cm2/Vs). This discrepancy is just one ...
Low-dimensional material based cold-source FET for logic Vdd scaling: Experimental Exploration KU Leuven
Low-dimensional materials, such as graphene, transition metal dichalcogenides and carbon nanotubes, have shown great potentialities in the field of electronics, and in particular as channel materials for field effect transistor. As we are approaching the post-silicon era, it is necessary to experimentally verify that the use of these materials can effectively overcome the current limitations of silicon-based transistors, such as the increase ...
Monte Carlo modelling of electron transport in low-dimensional materials KU Leuven
To improve electrostatic control, the channel thickness in ultra-thin body (UTB) transistors is reduced close to the atomic limit. However, when silicon and other bulk materials are scaled to these atomistic dimensions, their electron transport characteristics degrade through increased electron scattering, ultimately limiting device performance and efficiency. Two-dimensional materials, such as graphene, transition metal di-chalcogenides ...
Novel architectures for advanced sensing based on 2D materials platforms KU Leuven
Among forefront applications of 2D materials such as graphene (GR) and transition metal dichalcogenides (TMDs) the detection of sub-ppm concentrations of small molecules on a background of strongly interfering gas mixtures is currently challenging physics, chemistry and device engineering and requires an in-depth knowledge of molecule- surface interactions at the nanoscale. These materials provide a unique opportunity to discover new sensing ...
