Researcher at AMO GmbH, RWTH Aachen University, KTH Royal Institute of Technology, Senseair AB and the University of Bundeswehr have successfully developed a waveguide-integrated incandescent thermal mid-infrared emitter using graphene as the active material. This innovative approach significantly enhances the efficiency, compactness, and reliability of gas sensor systems, paving the way for widespread application across […]
Researchers from AMO GmbH and the Chair for Electronic Devices at RWTH Aachen University have experimentally demonstrated a scalable technique for realizing field-effect transistors based on two-dimensional molybdenum disulfide (MoS2), with low contact resistance (about 9 kΩ·µm) and high on/off current ratios of 108. The approach is based on lateral heterostructures of MoS2 and […]
One of the great assets of two-dimensional (2D) materials is the possibility of pacing different materials on top of each other to form heterostructures with properties tailored to specific application scenarios. However, the quality of the final material stack strongly depends on the electronic coupling between the different materials. Measuring this coupling in a non-destructive […]
Agata Piacentini and coworkers have demonstrated the first CMOS inverter based on transition metal dichalcogenides (TMDC) on a flexible substrate, using two distinct TMDC materials, MoS2 and WSe2. The team has successfully fabricated NMOS FETs based on CVD-MoS2 and PMOS FETs based on MOCVD-WSe2 on a flexible foil substrate. The FETs exhibited almost mirror-symmetric transfer […]
One of the big selling points of two-dimensional (2D) materials is their self-passivated nature, which allows them to be deposited on any substrate and opens up new possibilities for three-dimensional material stacks. The downside is their weak adhesion to the substrate, which can be a source of device instability. Quantifying the adhesion of 2D materials […]
Advanced applications such as smart patches and electronic skin have created the need for strain sensors that are not only sensitive and flexible, but also skin- and eco-friendly, and ideally self-healing, i.e. able to recover their sensing performance after damage. A successful strategy for implementing self-healing strain sensors is to combine a polymer with good […]
Researchers from RWTH Aachen University, AMO GmbH and Research Center Jülich have performed a detailed study of hBN based threshold memristors with nickel electrodes. Analyzing temperature-dependent transport measurements and high-resolution TEM images, they propose the formation and retraction of nickel filaments along boron defect in the h-BN film as the resistive switching mechanism. The study […]
RWTH Professor Max Lemme and colleagues from USA, China, and Belgium have proposed a set of clear guidelines for benchmarking key parameters and performance metrics of emergent field-effect transistors. The guidelines have been published as a Perspective Article in Nature Electronics.
Researchers from TU Wien, AMO GmbH, RWTH Aachen University and Wuppertal University have demonstrated a novel approach to enhance the electrical stability of two-dimensional transistors.
In a compact comment published in Nature Communications, Max Lemme and colleagues outline the most promising fields of applications of two-dimensional (2D) materials, as well as the challenges that still need to be solved to see the appearance of high-tech products enabled by 2D-materials.
