摘要：
In-situ deformation experiments were carried out in a transmission electron microscope to investigate the structural response, of single crystal GaAs nanowires (NWs) under. compression. A repeatable self-healing process was discovered in Which a partially's fractured GaAs NW restored its original single crystal structure immediately after an external compressive force was removed. Possible mechanisms of the self-healing process are discussed.
