Some materials exhibit a texture dominated by the alignment of a particular crystal direction with a given sample direction. This type of texture is often observed in thin films. For example, aluminum films often exhibit an alignment of <111> crystal directions with the film normal. Such a texture is commonly termed a (111) fiber texture. An ideal pole figure from such a film is shown in figure 1. X-ray rocking curves (see figure 2) are commonly used to characterize such textures. A rocking curve is essentially an intensity profile of the pole figure along an arbitrary line passing through the center of the pole figure. In the example used here we show only one half of the rocking curve, assuming the peak is centered about ??= 0°.
