Enhanced radiation tolerance of non-polar-terminated ZnO Academic Article uri icon

abstract

  • 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 (11 2 ̄ 0) and (10 1 ̄ 0) non-polar surface terminations. Possible defect interaction scenarios responsible for the enhanced radiation tolerance of non-polar-terminated ZnO are discussed. © 2013 AIP Publishing LLC.
