We report experimental observations of shell buckling instabilities in free-standing, verticallyaligned GaN nanotubes subjected to uniaxial compression. Highly uniform arrays of theGaN nanotubes standing on a GaN template were fabricated and subjected to uniaxialcompression using a nanoindenter. The buckling load was found to be of the order of150 µN for the GaN nanotubes with an outer radius of 40 nm, an inner radius of 20 nm, and heightsof 500 and 300 nm. Good agreement was found between the experimental observations, thestress–strain relation equation study findings and the predictions from the cylindrical shellbuckling theory.
