- Abstract
This paper presents research on the calculating analysis and experimental observations of shell buckling in individual gallium nitride hollow nanocolumns using nanoindentation. By using the experiment results of critical buckling strain under compression, we investigated the stiffness of hollow nanocolumns which were vertically aligned on a template by using linear elastic shell buckling theory. In addition, more studies of various possible nanomechanical behavior modes of gallium nitride hollow nanocolumns by shall model are provided. Furthermore, there was a comparison between nanocolumns by molecular dynamics simulation (one dimensional structure) and thin film by nanoindentation experiment (two dimensional structures). Finally, the buckling energy of compression for an individual gallium nitride hollow nanocolumn was also discussed.
