Single Crystals

Single crystal, any solid object in which an orderly three-dimensional arrangement of the atoms, ions, or molecules is repeated throughout the entire volume. A single crystal or monocrystalline solid is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries.

A single crystal or monocrystalline solid is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries. The absence of the defects associated with grain boundaries can give monocrystals unique properties, particularly mechanical, optical and electrical, which can also be anisotropic, depending on the type of crystallographic structure. These properties, in addition to making them precious in some gems, are industrially used in technological applications, especially in optics and electronics.

Single crystals are materials in which the entire sample has a continuous and unbroken crystal lattice to the edges of the sample with no grain boundaries. A single-crystal, or monocrystalline, solid is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries. Nov 26,  · Single crystal material produces broadband frequency response and higher sensitivity, permitting its use in harmonic imaging with minimal loss of the acoustic signal. It results in more uniform wide-bandwidth imaging and thus offers higher resolution images to the user.

Single crystal , any solid object in which an orderly three-dimensional arrangement of the atoms, ions, or molecules is repeated throughout the entire volume. Certain minerals , such as quartz and the gemstones, often occur as single crystals; synthetic single crystals, especially silicon and gallium arsenide, are used in solid-state electronic devices such as integrated circuits and light-emitting diodes LEDs.

In the preparation of synthetic single crystals, special techniques are employed to control the deposition of material upon one nucleus see nucleation , which often is a small single crystal of the substance obtained from a previous preparation.

Nucleation , the initial process that occurs in the formation of a crystal from a solution, a liquid, or a vapour, in which a small number of ions, atoms, or molecules become arranged in a pattern characteristic of a crystalline solid, forming a site upon which additional particles are deposited as….

Polycrystalline materials result when a substance solidifies rapidly; crystallization commences at many sites see nucleation , and the structurally ordered regions growing from each site intersect each other. The random arrangement of the boundaries between individual crystallites in a polycrystal causes them to….
