Homogeneity and variation of donor doping in Verneuil-grown SrTiO3:Nb single crystals
The homogeneity of Verneuil-grown SrTiO3:Nb crystals was investigated. Due to the fast crystal growth process, inhomogeneities in the donor dopant distribution and variation in the dislocation density are expected to occur. In fact, for some crystals optical studies show variations in the density of Ti(3+) states on the microscale and a cluster-like surface conductivity was reported in tip-indu...
متن کاملHazardous Doping for Photo-Electrochemical Conversion: The Case of Nb-Doped Fe₂O₃ from First Principles.
The challenge of improving the efficiency of photo-electrochemical devices is often addressed through doping. However, this strategy could harm performance. Specifically, as demonstrated in a recent experiment, doping one of the most widely used materials for water splitting, iron (III) oxide (Fe₂O₃), with niobium (Nb) can still result in limited efficiency. In order to better understand the ha...
متن کاملDesign of A Single-Phase Transformerless Grid-Connected PV Inverter Considering Reduced Leakage Current and LVRT Grid Codes
A new single-phase transformerless grid-connected PV inverter is presented in this paper. Investigations in transformerless grid-connected PV inverters indicate the existence of the leakage current is directly related to the variable common-mode voltage (CMV), which is presented in detail. On the other hand, in recent years it has become mandatory for the transformerless grid-connected PV inver...
متن کاملCurrent–Voltage Characteristics Across Small Angle Symmetric Tilt Boundaries in Nb-Doped SrTiO3 Bicrystals
Grain boundary structure and current–voltage (I –V ) characteristics were investigated for Nb-doped SrTiO3 bicrystals having small angle tilt boundaries with misorientation angles of 2◦ and 4◦ against [001]. The bicrystals were fabricated by using hot-joining technique at 1400◦C for 10 h under a pressure of 0.4 MPa. High resolution transmission electron microscopy study revealed that the joined...
متن کاملBODIPY-doped silica nanoparticles with reduced dye leakage and enhanced singlet oxygen generation
Photodynamic therapy (PDT) is a promising modality for cancer treatment. The essential element in PDT is the photosensitizer, which can be excited by light of a specific wavelength to generate cytotoxic oxygen species (ROS) capable of killing tumor cells. The effectiveness of PDT is limited in part by the low yield of ROS from existing photosensitizers and the unwanted side effects induced by t...
