Title: Enhanced radiation tolerance of non-polar-terminated ZnO

Room-temperature heavy-ion bombardment of polar (0001) ZnO leads to the formation of intermediate peak and step features in damage–depth profiles measured by ion channeling. Here, we show that these anomalous disorder effects are strongly suppressed for crystals with (1120) and (1010) non-polar surface terminations. Possible defect interaction scenarios responsible for the enhanced radiation tolerance of non-polar-terminated ZnO are discussed.
