Nucleation and Growth Mechanisms of 2D Semiconductor/high-k Dielectric Heterostacks KU Leuven
The extraordinary properties of the diverse two-dimensional (2D) materials are promising to improve existing technologies and create a wide range of new applications. 2D semiconductor/high-k dielectric heterostacks are of interest for applications in nanoelectronics and optoelectronics. Deposition of highly crystalline 2D semiconductors with monolayer thickness control on large-area substrates is essential to enable the applications. However, ...
Interface Engineering for Performance Enhancement in 2D Field Effect Transistors KU Leuven
2-dimensional (2D) semiconductors such as 2D transition metal dichalcogenides (MX2) have recently drawn much attention in the field of nano-electronics due to their potential for superior electrostatic control and heterogeneous integration. However, current MX2 devices suffer from high source and drain contact resistance, high defect density and low capacitance/charge build-up in the channel. To mitigate these challenges, it would be ...
Understanding Charge Behaviour in a 2D Transition Metal Dichalcogenide MOS System KU Leuven
Advancements in technology are driven by downscaling the channel length and
the thickness of semiconductor that improve performance of a MOSFET. 2D
semiconductors, like transition metal dichalcogenides (MX2), are van der Waals
(vdW) layered structures with one layer approx. 0.7 nm thick and self-terminated
surfaces with no dangling bonds. They offer the promise of ultrathin channels
with high mobility for future ...
Shapeable 2D magnetoelectronics by design Ghent University
Novel materials that couple advanced magnetic and electronic properties are paramount to sustain the hunger of the modern society for advanced consumer electronics and Internet of Things, yet reduce the energy consumption and environmental impact. To satisfy the rather versatile needs of wearable, flexible, integrable, bio-compatible, ever smarter, and low power electronics, the paradigm shift is needed - towards tailored heterostructures, ...
Nanoscale characterization and property evaluation of 2D polymers synthesized at the air-water interface KU Leuven
Polymers have permeated almost every sphere of modern life, from packaging to drug delivery, from 3D printing to airplanes. They consist of molecular chains in which smaller building blocks are connected via covalent bonds. So what is the next big thing for polymers? The answer lies in the arrival of two-dimensional (2D) materials which have dominated headlines in recent years. Graphene, a single atom thick sheet of carbon isolated at the ...

Versatile nanostructured functionalization of 2D carbon surfaces KU Leuven
Carbon-based materials form the backbone of many industrial applications such as chemical purification, separation technology and, gas adsorption and storage. The applicability of most of these materials, which are composed of two-dimensional (2D) sheets of sp2 hybridized carbon called graphene, is a result of their porosity and high surface area. A large variety of these come from natural sources and/or are produced in such a way that their ...
Unravelling the mechanism of on-surface 2D polymer formation at the liquid-solid interface: towards reliable and robust synthetic strategies KU Leuven
Polymers have permeated almost every sphere of modern life, from packaging to drug delivery, from 3D printing to airplanes. So, after being around for more than a century, what is the next big thing for polymers? The answer lies in the arrival of two-dimensional (2D) materials which have dominated headlines in recent years. Graphene, a single atom thick sheet of carbon isolated at the beginning of the century has several interesting ...
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 ...
