Abstract A study has been made of the effects of ion bombardment on copper surface morphology in a magnetron sputtering system using different glow discharge atmospheres of Ar, Ar/O2 and Ar/N2, respectively. The morphological features detected by the scanning electron microscope were: conical protrusions, etch pits, ripple and pillar structures. Conditions of cone formation were examined under the effects of: (1) ion dose, (2) gas type/content and (3) bombarding time. The results showed that treating copper in a mixture of (25% O2 + 75% Ar) d.c. glow discharge produced a surface of a high population of well-defined cones which may be utilized as a selective absorbing surface in solar thermal collectors or in other applications.
