STEXCU(TA) - SEED TEXTURING OF COPPER WITH TANTALUM SEED

The major intent of this study was to induce pyramid and/or cone surface texture and to identify different stages of the development of features on the surface according to primary and secondary effects. To obtain a pyramid (cone) texture, the STex technique has been applied. This means that a low sputtering yield seed material (tantalum plate in this case) was located in the proximity of the copper target and at about 0. 5 rad angle wth respect to the ion beam axis. The accelerating voltage used in the experiments was 800 v.
