Temperature-dependent mechanical-resonance frequencies and damping in ensembles of gallium nitride nanowires

(author unknown)



J. R. Montague, K. A. Bertness, and N. A. Sanford et al.

We have measured singly clamped cantilever mechanical-resonances in ensembles of as-grown gallium nitride nanowires (GaN NWs), from 12 K to 320 K. Resonance frequencies are approximately linearly dependent on temperature near 300 K with relative shifts of 40 ± 20 ppm/K, consistent with temperature ... [Appl. Phys.
