Herein we report on the synthesis of a metastable (Cr,Y)2AlC MAX phase solid solution by co-sputtering from composite Cr-Al-C and elemental Y target, at room temperature, followed annealing. While direct high-temperature resulted in multiphase films, as evidenced X-ray diffraction analyses, temperature depositions, annealing to 760 {\deg}C led formation pure diffusion. Higher temperatures cause...

Phase-change materials (PCMs) are the cornerstone for development of reconfigurable and programmable photonic devices. Sb 2 S 3 has been recently proposed as an interesting PCM due to its low-losses in visible near-IR. Here, we report use imaging polarimetry spectroscopic ellipsometry reveal directly measure optical properties both crystalline amorphous states obtained upon crystallization by a...

Generally, the phase retrieval problem can be viewed as reconstruction of a function/signal from only magnitude linear measurements. These measurements be, for example, Fourier transform density function. Computationally is very challenging. Many algorithms are based on i.i.d. Gaussian random However, remain one few classes In this paper, we develop an efficient algorithm sub-Gaussian frames. W...

Studies of the heat capacity and dielectric properties (1-x)BiFeO 3-x PbFe 0.5 Nb O 3 ceramic multiferroics in temperature range 300-800 K were carried out. Based on studies concentration dependences constant, phase transition temperatures system determined. (1-x)PbFe with various x concentrations. It is shown that an increase component, ferroelectric antiferromagnetic transitions BiFeO shift t...

Abstract The Bi 2 O 3 –ZnO system is of interest for optimization the electro‐ceramic synthesis process. There are some limitations and conflictions in experimental studies phase diagram literature. In this work, five compositions were prepared characterized. 38 ZnO 58 compound was confirmed, its heat capacities transformation properties detected. A thermodynamic description carried out based o...
