This structure consists of two superimposed row-oriented crystalline textures, i.e. an MD-stacked texture and a TD-stacked texture. The lamellar populations in the two structures are affected greatly by the neck height of the film blowing process. The MD-stacked crystalline texture is found to be a c-texture. The trends in the mechanical ...

In general, crystalline ceramics also are more complex. CELLS VS PRIMITIVE CELLS. In the literature we often find reference to unit cells and to primitive cells. The primitive cell may be defined as a geometrical shape which, when repeated indefinitely in three dimensions, will fill all space and is the equivalent of one atom. The unit cell ...

Optical functional film with triangular pyramidal texture for
1. Introduction. Reducing the reflection loss and enhancing the photovoltaic effect are effective ways of improving the efficiency of crystalline silicon cells (Chen et al., 2018, Wu et al., 2017).Aiming at reducing the reflection loss on the surface of crystalline silicon cells, optical functional textures (i.e., textured surfaces) can be directly fabricated …
Texture_(crystalline)
Texture (crystalline) In materials science, texture is the distribution of crystallographic orientations of a sample. A sample in which these orientations are fully random is said to have no texture. If the crystallographic orientations are not random, but have some preferred orientation, then the sample has a weak, strong, or moderate texture.
Texture (Crystalline) | Encyclopedia MDPI
0. In materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric). A sample in which these orientations are fully random is said to have no distinct texture. If the crystallographic orientations are not random, but have some preferred orientation, then ...
Texture engineering of mono-crystalline silicon via alcohol …
Control of texture structures is an effective method to reduce surface reflectivity and enhance the efficiency of solar cells. In this paper, pyramid structures are prepared on mono-crystalline silicon wafers by cyclodextrin as surfactant to slow down the etching rate in alcohol-free alkali solution.

IgnRx Study Guide
Crystalline Textures. Population sizes of crystals in igneous rocks. Molten rock may cool more slowly when confined to underground environments, and more quickly when erupted at the surface of the earth. The rate at which molten rock cools controls the eventual size distribution of crystals in igneous rock.

5.5: Classification of Sedimentary Rocks
Crystalline Limestone. Crystalline limestone is a carbonate sedimentary rock that is composed of the precipitation of the mineral calcite ((ce{CaCO3})) from saturated sea water. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ((ce{CaCO3})). About 10% of sedimentary …
