A strained Ge quantum well, grown on a SiGe/Si virtual substrate and hosting two electrostatically defined hole spin qubits, is nondestructively investigated by synchrotron-based scanning X-ray diffraction microscopy to determine all its Bravais lattice parameters. This allows rendering the three-dimensional spatial dependence of the six strain...

Future medical X-ray imaging will benefit from advances in computing power and artificial intelligence as well as improvements in the X-ray detector performance itself. Hybrid inorganic-organic perovskite materials promise direct conversion detectors with higher image quality, owing to their strong X-ray absorption, high electron and hole...

We study by in-situ X-ray diffraction (XRD) in a unique, custom-made furnace mimicking an industrial setup, the effect of pre-annealing on electroplated and sputtered thin films of Cu-In-Ga, as precursor material for Cu(In,Ga)(S,Se)2 (CIGS)-based solar cells. In the first part of the paper, the properties of the as-deposited precursors are...

To realize the potential of artificial intelligence in medical imaging, improvements in imaging capabilities are required, as well as advances in computing power and algorithms. Hybrid inorganic–organic metal halide perovskites, such as methylammonium lead triiodide (MAPbI3), offer strong X-ray absorption, high carrier mobilities (μ) and long...

The selenisation of Cu-Ga-In metallic precursors is investigated by in-situ X-Ray Diffraction (XRD) in a selenisation tool which mimics at the laboratory scale an industrial tool (thus fully scalable) and allows fine control over the selenisation parameters and reproducibility. In this setup, the interdiffusion of Ga and In was significantly...

Understanding the three-dimensional variability of unidirectional composites is relevant to the material per formance and the development of advanced material modelling strategies. This work proposes a new method ology for the characterization of unidirectional composites, showcased on carbon fibre/poly(ether-ether-ketone) tapes. Three...

The new generation compact X-ray source for semiconductor metrology requires a brilliance that is higher than existing technology can offer. In this report, we propose a new X-ray source where an electron beam is focused on a rotating liquid metal anode. We assume that high brilliance emission can be achieved with power densities up to 10 MW/mm2...

Perovskite semiconductors hold a unique promise in developing multijunction solar cells with high-efficiency and low-cost. Besides design constraints to reduce optical and electrical losses, integrating several very different perovskite absorber layers in a multijunction cell imposes a great processing challenge. Here, we report a versatile two...

Magnetron sputtering is widely used for deposition of silicon oxynitride (SiOxNy) coatings on glass in large-area applications. Since repeated deposition simulates the factory-scale in-line processing, amorphous aluminum-doped SiOxNy layers with thickness of about 250 nm were deposited by reactive pulsed DC sputtering in a multi-pass process...

EBL2 is TNO's platform for EUV exposure testing and surface analysis. EBL2 is capable of generating conditions relevant to EUV mask operation at all foreseen source power nodes. The authors describe how TNO performs a customized (accelerated) lifetime test on EUV masks. The required gas, EUV, and thermal parameters will be considered, and...

In this paper, we present an electromagnetic full-wave modeling framework, as a support EM tool providing data sets for X-ray ptychographic imaging. Modeling the entire scattering problem with Finite Element Method (FEM) tools is, in fact, a prohibitive task, because of the large area illuminated by the beam (due to the poor focusing power at...

Due to its potential for high resolution and three-dimensional imaging, soft X-ray ptychography has received interest for nanometrology applications. We have analyzed the measurement time per unit area when using soft X-ray ptychography for various nanometrology applications including mask inspection and wafer inspection, and are thus able to...

Optical components such as diffraction gratings are widely used in Space-flight satellites to analyse light properties from soft-X rays to Infra-Red. The diffraction gratings are one of the key optical components of space-flight instruments and have to exhibit very high optical performances. TROPOMI (Tropospheric Monitoring Instrument) is a...

To date there is no consensus about the most appropriate analytical method for measuring carbon nanotubes (CNTs), hampering the assessment and limiting the comparison of data. The goal of this study is to develop an approach for the assessment of the level and nature of inhalable multi-wall CNTs (MWCNTs) in an actual workplace setting by...

Unencapsulated CIGS solar cells were simultaneously exposed to damp heat and illumination. In-situ monitoring of their electrical parameters demonstrated a rapid decrease of the efficiency, mainly driven by changes in the series and shunt resistances. The non-degraded and degraded solar cells were studied by SIMS and XRD to investigate the...

We made and characterized an X-ray detector on a 25-ìm-thick plastic substrate that is capable of medicalgrade performance. As an indirect conversion flat panel detector, it combined a standard scintillator with an organic photodetector (OPD) layer and oxide thin-film transistor backplane. Using solution-processed organic bulk heterojunction...

Modification of the absorber surface properties by Cd2+ treatment (Cd2+ partial electrolyte) results in the following: formation of Cd(OH)2 on the absorber surface, deposition of thinner chemical bath-deposited CdS buffer layer, and a smaller space charge region. The impact on electrical performances is as follows: decrease of the series...
