Study of the Thermal Properties and Lattice Disorder Effects in CdTe–Based Crystals: CdBeTe, CdMnTe, and CdZnTe

Crystals, 2022
Mixed semiconductor ternary crystals were grown using the Bridgman–Stockbarger method. This is a high–temperature and high–pressure crystal growth method. Cd1–xBexTe crystals were grown in the range of composition 0 < x < 0.1, such as 0.00, 0.01, 0.03, 0.

X-Ray and Thermal Studies on ZnxMg1-x SO4.7H2O Crystals

E-Journal of Chemistry, 2010
Single crystals of pure and mixed ZnSO4.7H2O and MgSO4.7H2O crystals were grown by slow evaporation method. The grown crystals were characterized by x-ray diffraction, atomic absorption spectral analysis and thermal analysis.

Influence of cation substitution on optical constants of (Cu1-xAgx)7SiS5I mixed crystals

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2020
(Cu1–хAgx)7SiS5I mixed crystals were grown using the vertical zone crystalliza-tion method, they have been shown to crystallize in cubic structure (). The diffuse reflection spectra for the powders of (Cu1–хAgx)7SiS5I mixed crystals were measured at room

Seeking Rules Governing Mixed Molecular Crystallization [PDF]

Crystal Growth & Design, 2022
Mixed crystals result when components of the structure are randomly replaced by analogues in ratios that can be varied continuously over certain ranges. Mixed crystals are useful because their properties can be adjusted by increments, simply by altering the ratio of components.

Characterization of the Spatial Distribution of the Thermodynamic Phase Within Mixed‐Phase Clouds Using Satellite Observations

Geophysical Research Letters, 2023
Models assume that mixed‐phase clouds consist of uniformly mixed ice crystals and liquid cloud droplets when observations have shown that they consist of clusters, or “pockets,” of ice crystals and liquid cloud droplets.

Ellipsometric studies of (Cu6PS5I)1-x(Cu7PS6)x and (Cu6PS5Br)1-x(Cu7PS6)x mixed crystals

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2019
(Cu6PS5I)1–x(Cu7PS6)x and (Cu6PS5Br)1–x(Cu7PS6)x mixed crystals were grown using a direct crystallization technique from the melt. Refractive indices and extinction coefficients for mixed crystals were obtained from the spectral ellipsometry measurements.

Flexible Förster resonance energy transfer‐assisted optical waveguide based on elastic mixed molecular crystals

Aggregate, 2023
Flexible molecular crystal waveguides based on elastic molecular crystals (EMCs) are essential in flexible and compact optical materials. An increased loss coefficient α due to self‐absorption is often a problem in optical waveguides (OWGs) of ...
