Plasma provides specific adjustment of solid-state surface properties offering an alternative to high temperature treatment. In this work, hydrogen plasma treatment of monocrystalline (0001) ZnO surface is studied in an inductively coupled plasma (ICP) reactor with reduced capacitively coupled plasma mode. We explain the crucial role of electrical grounding of the sample holder for plasma etching and related changes in the morphology, optical and electrical properties of surfaces exposed to electron and ion bombardment. The effects on the chemical composition of the surface are analyzed by (XPS), optical properties by photoluminescence spectroscopy, topography, roughness and surface potential by atomic force microscopy (AFM) and Kelvin probe force microscopy (KPFM). All methods show altered ZnO surface properties before and after plasma treatment strongly depending on the electrical potential of the holder.
