Pleased to share our latest publication – congrats to first author Tunahan Gök for driving this work forward. In this work, we present single-mode waveguides fabricated from evaporated amorphous Al₂O₃, achieving propagation losses as low as 0.68 ± 0.03 dB/cm at 405 nm. The waveguides, produced using a Cr hard mask and EBL on a 3 µm […]
We are excited to share the latest research by Lukas Völkel and collaborators from Lehrstuhl für Elektronische Bauelemente (ELD), Forschungszentrum Jülich, AIXTRON SE, and AMO GmbH, recently published in npj 2D Materials and Applications. 🔬 The study explores the influence of humidity on the resistive switching behavior of hexagonal boron nitride (h-BN)-based memristors. The devices […]
Mach-Zehnder interferometers (MZIs) are key components of modern photonic circuits, with applications ranging from optical computing and artificial intelligence to sensing and quantum optics. These applications increasingly require complex networks of MZIs that operate efficiently over a broad frequency range, with low insertion loss and minimal power consumption. In a recent study, Jens Samland and […]
A collaboration between AMO GmbH and Fraunhofer IAF demonstrates the potential of sputtered aluminum nitride for photonic applications in the telecom spectrum. Aluminum nitride (AlN) is emerging as an outstanding material for photonic waveguide applications. The best results to date have been achieved with AlN grown by metal organic chemical vapor deposition (MOCVD), while sputtered […]
Using cutting-edge transmission electron microscopy (TEM) techniques, researchers from RWTH Aachen University, Forschungszentrum Jülich and AMO GmbH have revealed unprecedented details about the reversible phase transition of ceria – a material that holds huge potential for catalytic applications, energy generation, as well as for memristive devices – showing that this can be precisely manipulated with […]
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 […]
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 […]
