	abstract = {In situ spectroscopic ellipsometry and ex situ structural investigations were performed on annealed amorphous Ga2O3 thin films prepared by radio frequency sputtering. The change of the optical parameters was monitored during the annealing in air. In situ ellipsometry was shown to be a valuable method to determine the phase transition temperatures of Ga2O3 during annealing in ambient conditions. X-ray diffraction and transmission electron microscopy revealed that the initially amorphous film first crystallizes into the metastable γ-Ga2O3 phase, which transforms into the β-Ga2O3 phase at higher temperatures. Optical transmittance measurements were used to determine the optical bandgap of the layers at the different annealing steps. Photoluminescence experiments were performed on the samples after annealing at varying temperatures and atmospheres. After the initial formation of the γ-Ga2O3 phase a broad green luminescence band emerged, while after the transformation to the β-Ga2O3 phase blue or red emission was observed depending on the annealing atmosphere.},

	abstract = {A compact electrochemical sensor module for pH detection was developed for potential integration into specialized devices used for live cell or tissue incubation, for applications in highly parallelized cell culture analysis, by incorporating Organ-on-Chip devices. This research focuses on the deposition, structural and chemical analysis, and functional characterization of different titanium-oxide layers with various compositions as potentially sensitive materials for pH sensing applications. The titanium-oxide layers were deposited using vacuum sputtering and atomic layer deposition at 100 °C and 300 °C, respectively. Transmission electron microscopy and X-ray photoelectron spectroscopy were utilized to determine the specific composition and structure of different titanium-oxide layers. These TiOx-functionalized electrodes were connected to the application-specific analog front-end chip of the low-power readout circuit for precise evaluation. The pH sensitivity of the differently modified electrodes, employing various TiOx materials, was evaluated using pH calibration solutions ranging from pH 6 to 8. Among the various deposition solutions, such as sputtering or high-temperature atomic layer deposition, the TiOx layer deposited using low-temperature atomic layer deposition proved more suitable for pH sensing applications, with a sensitivity of 54.8–56.7 mV/pH, which closely approximates the Nernstian response.},

In particular, the incorporation of sulfur (S) in the 4H-SiC near-surface region was observed at the process performed at 800 °C, without any significant effect on the surface morphology. On the other hand, Ni4H-SiC Schottky contacts fabricated on the sulfurized 4H-SiC surface showed a 0.3 eV reduction of the average barrier height with a narrower distribution, with respect to the untreated sample. These results were explained by an increase of the 4H-SiC electron affinity after sulfurization, and a Fermi level pinning effect.},

	abstract = {Copper sulfides represent a broad range of chemical compounds, including naturally occurring minerals and wet-chemically synthesized nanoparticles. Tailoring the size, shape, and chemical composition of Cu2-x S nanoparticles enables the tuning of their optical and electronic properties allowing the switch between semiconducting and plasmonic characteristics. While the sulfidation of metals and metal oxides can even occur spontaneously under ambient storage conditions, the targeted synthesis of Cu2-x S nanoparticles mostly relies on the use of inorganic sulfur compounds. Inspired by the natural sulfidation reactions, a novel approach is developed in this paper to transform sacrificial Cu2O nanooctahedra by a short-chain organic thiol (beta-mercaptoethanol) into spherical Cu2S superstructures consisting of phase-pure Cu2S quantum dots. The optical and photoelectrochemical properties are thoroughly investigated and supplemented by advanced electron microscopy analysis to identify the phase of the superstructure building blocks. Structural and surface analyses reveal that the superstructures are composed of small (4-5 nm) Cu2S quantum dots spatially separated by a thin amorphous ligand layer. The results highlight the dual role of beta-mercaptoethanol serving both as a sulfur source and as a stabilizing ligand upon superstructure formation. To synthesize semiconductor/metal multicomponent nanostructures, the surface of the superstructures is decorated with Au nanograins initiated by the photoreduction of aqueous Au3+ ions. Upon the fabrication of working electrodes from the developed superstructures, the p-type nature of the Cu2S is demonstrated by open-circuit potentiometry. Superstructures supply negative photocurrent under UV irradiation, which can be further enhanced by the presence of Au nanograins. Using the developed synthetic method, phase-pure photofunctional nanomaterials can be prepared by the sulfidation of cuprous oxide in a controlled manner.},
