However, how they change the mechanical performance remains unclear.

GaN nanowires with a higher point defects density demonstrate lower Young's modulus and fracture strength as well as noticeable time\u2010dependent anelastic behavior under the stress gradient. Whereas, the \u201ccleaner\u201d nanowires are much stronger and remain elastic without detectable hysteresis. Photoluminescence spectroscopy analysis indicates that the dominant point defects in the unintentionally doped GaN nanowires are Ga vacancies and the complex with O atoms at N sites. The observed \u201csmaller\u2010is\u2010stronger\u201d size effect aligns with the size\u2010dependent point defect density in both types of nanowires. This work may clarify the longstanding inconsistencies regarding the elastic properties of GaN nanowires and serve as an example of how mechanical behaviors can be tailored through defect engineering.\n                  <\/jats:p>","DOI":"10.1002\/smll.202412486","type":"journal-article","created":{"date-parts":[[2025,5,16]],"date-time":"2025-05-16T06:04:08Z","timestamp":1747375448000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of Native Point Defects on Elastic Properties of GaN Nanowires"],"prefix":"10.1002","volume":"21","author":[{"given":"Le","family":"Wang","sequence":"first","affiliation":[{"name":"Center for Advancing Materials Performance from the Nanoscale (CAMP\u2010Nano) &amp; Hysitron Applied Research Center in China (HARCC) State Key Laboratory for Mechanical Behavior of Materials Xi'an Jiaotong University  Xi'an 710049 P.
