   abstract = {Refractory transition metal nitrides are attracting attention in many microelectronics research and development fields. Their different applications and desired performances require a precise control of the film thickness and elemental depth profile. This information can be non-destructively obtained combining Grazing-Incidence X-ray Fluorescence (GIXRF) and X-ray Reflectometry (XRR) analysis. GIXRF-XRR joint analysis can be performed following a reference-free approach, which requires the knowledge of the whole experimental system. However, such a rigorous metrological approach cannot be easily applied to in-lab or in-fab tools due to the difficulty to access the various experimental set-up parameters, therefore another approach is needed. In this paper, we used a reference-based method consisting in the use of known standard samples, close in composition and structure with respect to the samples to analyse, to deduce the key parameters of the instrumental setup. These are then used to perform quantitative GIXRF-XRR combined analysis of the samples of interest. We applied this method to titanium tungsten nitride thin films elaborated by Physical Vapour Deposition (PVD). Our results show that the reference-based method, using carefully determined instrumental functions, can meet the requirement for both qualitative and quantitative depth-profiling analysis. The reference-based approach result easier to implement into labs and fabs than the reference-free method.},

   abstract = {Cu(In,Ga)Se2 photovoltaic technology has notably progressed over the past years. Power conversion efficiencies above 23\% were reached in spite of the polycrystalline nature of the absorber. Although efficiencies are still far from the practical limits, the material quality is approaching that of III–V compounds that yield the most efficient solar cells. The high carrier lifetime, low open circuit voltage deficit and external radiative efficiency in the single-digit percentage range suggest that the next efficiency boost may arise from the implementation of alternative device architectures. In this perspective paper, we describe the current challenges and pathways to enhance the power conversion efficiency of Cu(In,Ga)Se2 solar cells. Specifically, we suggest the use of non-graded absorbers, integration of charge selective contacts and maximization of photon recycling. We examine these concepts by a semi-empirical device modelling approach, and show that these strategies can lead to efficiencies of 29\% under the AM1.5 global spectrum. An analysis of whether or not current state-of-the-art Cu(In,Ga)Se2 solar cells already benefit from photon recycling is also presented.},

   abstract = {Hydrogen features a very high specific energy density and is therefore a promising candidate for clean fuel from renewable resources. Water electrolysis can convert electrical energy into storable and transportable hydrogen gas. Under acidic conditions, platinum is the most active and stable monometallic catalyst for the hydrogen evolution reaction (HER). Yet, platinum is rare and needs to be used efficiently. Here, we report a synthesis concept for colloidal bimetallic platinum–ruthenium and rhodium–ruthenium nanoparticles (PtRuNP, RhRuNP) and their incorporation into ordered mesoporous carbon (OMC) films. The films exhibit high surface area, good electrical conductivity and well-dispersed nanoparticles inside the mesopores. The nanoparticles retain their size, crystallinity and composition during carbonization. In the hydrogen evolution reaction (HER), PtRuNP/OMC catalyst films show up to five times higher activity per Pt than Pt/C/Nafion® and PtRu/C/Nafion® reference catalysts.},

   abstract = {The 3D nanostructure of organic materials plays a key role in their performance in a broad range of fields, from life sciences to electronics. However, characterising the functionality of their morphologies presents a critical challenge requiring nanometre resolution in 3 dimensions and methods that do not excessively distort the soft matter during measurement. Here we present scanning probe tomography using a commercial Pt-Ir coated tip and controlling the tip loading force to sequentially characterise and remove layers from the surface of a sample. We demonstrate this process on a sample exhibiting a polymer nanowire morphology, which is typically used for organic electronic applications, and present a tomographic reconstruction of the nanoscale charge transport network of the semi-crystalline polymer. Good electrical connectivity in 3D is demonstrated by directly probing the electrical properties of the inter-nanowire charge conduction.},

   abstract = {To gain an in-depth understanding of the mechanisms and driving forces responsible for the microstructural changes during the Cu-Se deposition of the three-stage Cu(In,Ga)Se 2 co-evaporation process and its effect on the absorber quality, we have performed a series of in-situ studies as well as complementing ex-situ studies in the recent past. Our studies provide insights into several correlating changes of the structural and physical properties of the absorber layer during Cu-Se deposition or subsequent annealing, such as defect annihilation, stress relaxation, texture changes, and grain growth. In this contribution, we combine these various observations and discuss how they can be explained by a model of abnormal grain growth, driven by differences in the defect densities of neighboring grains.},
