single crystal
A single crystal is a material where the atoms are arranged in a continuous, orderly pattern throughout the entire solid, without any boundaries or gaps. This uniform structure allows for consistent properties, like electrical conductivity or strength, in all directions. Single crystals are often used in high-performance electronics, such as semiconductor wafers in computer chips, because their perfect internal order enables precise control over electrical behavior. Unlike polycrystalline materials, which are made of many small crystals with boundaries between them, single crystals have a single, unified structure that provides unique and predictable physical properties.
