High-yield fabrication of suspended graphene membranes

Researchers from the Chair for Electronic Devices at RWTH and at AMO GmbH have demonstrated a method for fabricating large-scale arrays of micro cavities sealed by graphene membranes with high yield. High mechanical strength, extreme thinness and exceptional hermeticity make graphene an ideal material for the realisation of micro- and nanoelectromechanical systems based on suspended […]

nanovate! #8 is here – happy reading!

The latest issue of AMO’s magazine is finally out.  In this edition, we dive deep into sustainability, exploring how nanotechnology can drive a successful energy transition and pave the way for a more sustainable future. We also celebrate the success of AMO’s youngest startup, Black Semiconductor, and we introduce INFRACHIP, an EU initiative that grants […]

A scalable method to reduce the contact resistance of graphene

The exceptional electronic properties of graphene make it a material with large potential for low-power, high-frequency electronics. However, the performance of a graphene-based device depends not only on the properties of the graphene itself, but also on the quality of its metal contacts. The lack of effective and manufacturable approaches to establish good ohmic contacts […]

A graphene-based infrared emitter for integrated photonic gas sensors

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 […]

A scalable approach for MoS 2-field-effect transistors with low contact resistance

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 […]

MultiLab: a lab-on-chip platform for chemical and biochemical analysis

AMO GmbH is proud to be one of the partners of MultiLab, an EU project that aims at developing a lab-on-chip platform designed to meet the growing demand for small, versatile sensors able to provide chemical and biochemical information. Analysis methods like chromatography and microscopy are essential working horses of medical diagnostics and environmental monitoring. […]

A non-destructive method to probe inter-layer coupling on millimeter-scale graphene-MoS2 heterostructures

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 […]

INFRACHIP – An EU initiative to grant user access to state-of-the-art cleanroom facilities

Do you have an idea for a new high-tech product but lack the in-house technology to develop a prototype? INFRACHIP could be the solution you are looking for! INFRACHIP is an initiative funded by the European Union to finance user access to state-of-the-art cleanroom facilities distributed all over Europe, supporting pathfinding research in semiconductor technology. […]

Institutional visit to Piedmont

Prof. Max Lemme has visited Piedmont as part of an industry/academic delegation headed by Mona Neubaur, Minister for Economic Affairs, Industry, Climate Action and Energy of North-Rhine Westphalia (NRW).   The visit, initiated by Piedmont’s councilor for industry, Andrea Tronzano, had the aim of contributing to developing common relationships and policies in the microelectronics sector […]
