Single-Photon-Counting Detection for Soft X-rays Down to 530 eV
The PSI Photon Science Detector Group has developed the first single-photon-counting pixel detector capable of detecting soft X-rays down to 530 eV. This breakthrough was achieved by combining EIGER readout chips with novel inverse LGAD sensors, developed in collaboration with and fabricated at Fondazione Bruno Kessler (Italy). The detector is now in user operation for ptychographic applications, where it has already enabled significant scientific results at the Fe L₃-edge (707 eV) and even at the O K-edge (530 eV), demonstrating superior detection performance compared to commercially available state-of-the-art detectors.
Measuring How Molecules Communicate
A collaboration between PSI and the University of Vienna has resulted in a new experimental method that, for the first time, enables the direct measurement of partial charges in molecules. Partial charges are fundamental to understanding molecular structure, interactions, and reactivity, yet until now no general technique existed to determine them experimentally.
Aperiodic Chiral Tiling by Molecular Self-Assembly
The 2D self-arrangement of a molecule that resembles three-armed spirals leads to a triangular pattern that is effectively aperiodic.

Recognition at MNE 2024 Micrograph Contest
The MNE conference is the flagship event of the International Society for Micro- and Nanotechnology (iMNEs). The research fields covered by the MNE conferences have consistently driven advancements in the development of smaller and smaller structures. To emphasize the significance of micrographs in this field, the conference features a micrograph contest, sponsored and hosted by Zyvex Labs. Entries are judged based on both their technological relevance and artistic merit.
This year, Peng Qi from the X-ray Nano Optics group, LXN, CPS, earned third place and an honorable mention for his two submitted images.

Novel Photoresist Chemistry Enables Lithography Approaching Angstrom-Scale Resolution
Photoresist materials are crucial in the manufacturing of computer chips, where the circuits are initially printed in the photoresist using photolithography. As the demand for smaller and more precise circuitry in computer chips grows, photoresists must resolve features with smaller sizes and higher density. One of the factors determining the ultimate resolution in lithography is the molecular size/mass of the photoresists.
