2D transition metal dichalcogenides for beyond silicon logic devices: improving the Metal/MoS2 interface through molecular doping. KU Leuven
2D materials have demonstrated enormous potential for a great number of applications such as sensors, spintronic, superconductors, and (photo)electronic devices. From these 2D materials, semiconducting transition metal dichalcogenides (MX2) are of special interest for electronic logic devices such as Field Effect Transistors (FETs), given their interesting properties such as ultra-thin bodies and high electronic band gap that could enable ...
Contact to Semiconducting Transition Metal Dichalcogenides KU Leuven
The CMOS industry has made great strides in achieving enormous computational power by downscaling the metal oxide semiconductor field-effect transistors
(MOSFETs). Various technological innovations have been instrumental in achieving this transistor miniaturization. This scaling is reaching its limits
as short channel effects (SCE) significantly degrade the device performance. To enhance the electrostatic control and overcome SCE, ...
Synthesis of few layered transition metal dichalcogenides by ion implantation (SIMPLANT). KU Leuven
The SIMPLANT proposal addresses point 1 of the topic descriptions of the Graphene JTC areas, namely, "Synthesis and characterization of Layered Materials (LMs) beyond graphene". We propose a novel, large-scale method, based on ion implantation, for the controlled synthesis of few-layer transition metal dichalcogenides (TMDCs) of general formula MX2, where M is the transition metal and X the chalcogen element. Ion implantation is a highly ...
Finite-Difference Time-Domain (FDTD) Modelling Algorithms for Transition Metal Dichalcogenides (TMDCs) in Nanoelectronic, Spintronic and Valleytronic Devices Ghent University
Two-dimensional (2D) materials attract a lot of interest for the development of novel nanoelectronic devices, owing to their monolayer nature, which allows for integration in planar devices. The most well-known example of such a material is graphene. Another class of 2D materials are transition metal dichalcogenides (TMDCs), which exhibit similar properties as graphene (superior carrier mobility, high cut-off frequency, etc), but are still ...

Nanostructuring transition metal dichalcogenides via non-covalent and covalent molecular functionalization KU Leuven
Graphene is a two-dimensional material that exists of a single layer of carbon atoms. It relates to the natural material, graphite, that is composed of a huge number of stacked graphene layers, just like a phone book consists of a stack of pages. However, the electrical properties of a single graphene layer differ a lot from those of graphite. This insight gave rise to the birth of the so-called two dimensional materials, or 2D materials. ...
Metrology and physical mechanisms of 2D transition metal dichalcogenides and devices. KU Leuven
Electronic devices surrounding us are getting faster and smarter at a very fast pace. One major enabler of this process is that transistors, i.e. the unit cell of these electronic devices, has been continuously scaled down, recently transitioning from a planar form to a three-dimensional design: FinFETs. Unfortunately, they are predicted to reach their limits within 5 years, posing the need for a new technology to fuel future nanoelectronics ...
Time-resolved optical microscopy techniques to characterize 2D transition metal dichalcogenides KU Leuven
2D transition metal dichalcogenides (TMDs) hold great potential for application in different fields, in particular in nanoelectronics and photonics. In nanoelectronics, large energy dissipation due to heating in chips is unsustainable in terms of both costs and performance drop and 2D TMDs hold great potential to alleviate these problems. In photonics, the integration of 2D TMDs is predicted to enhance the energy harvesting. Towards such ...
