Texture and secondary extinction of vacuum deposited Ag films

In the present work the texture of vacuum evaporated Ag films have been studied using standard X-ray texture diffractometer techniques. It is shown that these films have a rather sharp multicomponent texture: a main 〈111〉-component accompanied with twin-related 〈511〉-component and weak 〈100〉-component. The effect of secondary extinction is evaluated on the 111-pole figures. In order to avoid the systematic error due to extinction the volume fractions are calculated from 200-pole figures where the extinction effect is much smaller compared to that of the former one. Therefore, the correct evaluation and the interpretation of the structural properties requires secondary extinction to be taken into account.
