Home > Blossary: Defects in Materials
Defects determine many properties of materials (those properties that we call "structure sensitive properties"). Even properties like the specific resistance of semiconductors, conductance in ionic crystals or diffusion properties.

All crystals whose structures can be described by layers are prone to stacking faults. A stacking fault is any defect that alters the periodic sequence of layers. These defects may be a wrong layer inserted into the sequence, a change of the layer sequence or a different translation between two subsequent layers. These defects may affect the whole crystal or a finite region if e.g. an additional layer is present between an otherwise perfect sequence of layers.

Todos los cristales cuyas estructuras pueden ser descritos por capas son propensos a fallas de apilamiento. Una falla de apilamiento es cualquier defecto que altera la secuencia periódica de capas. Estos defectos pueden ser una capa mal insertada en la secuencia, un cambio de la secuencia de la capa o una traducción diferente entre dos capas posteriores. Estos defectos pueden afectar el cristal entero o una región finita, si por ejemplo una capa adicional está presente entre una secuencia perfecta de capas.
