In this work, nanocomposites made of nanosized zirconia crystallized in situ in an amorphous silicon oxycarbo(nitride) (SiOC(N)) matrix have been designed through a precursor route for visible light photocatalytic applications. The relative volume fraction of the starting precursors and the pyrolysis temperatures not only influences the phase fract...
In this article, we present a computationally efficient homogenization technique for linear coupled diffusion–mechanics problems. It considers a linear chemo-mechanical material model at the fine scale, and relies on a full separation of scales between the time scales governing diffusion and mechanical phenomena, and a relaxed separation of scales ...
Digital transformation in manufacturing is one of the key megatrends in the development of the global economy and society. Three-dimensional (3D) printing is a transformative digital technology poised to disrupt manufacturing and supply chains across major industries. Here we critically examine relevant insights into current and emerging applicatio...
In this paper, we investigate the effect of thermal annealing on nonradiative recombination parameters ofGaAsPN materials used for intermediate band solar cells. This study is performed thanks to photothermaldeflection technique PTD. Indeed, nonradiative lifetime, electronics diffusivity, surface and interface recombination,are extracted through a ...
Open-Circuit Voltage Decay (OCVD) method was investigated for few decades as a simple and convenient method to characterize effective lifetime into Ge and Si p-n homojunctions. Minority carrier lifetime (MCL) is an important parameter to optimize device design where being able to investigate one type of carriers is an important goal. The p-n homoju...
