Elastic modulus and resonance behavior of boron nitride nanotubes
2004
Applied Physics Letters
Preserved Fulltext
The effective elastic modulus (E) of boron nitride nanotubes ͑BNNTs͒ was measured using the electric-field-induced resonance method inside a transmission electron microscope. The average value of E from the measurements of 18 individually cantilevered BNNTs was 722 GPa, comparable to the theoretical estimate of ϳ850 GPa. No strong variation of E with the diameter of the BNNTs, which spanned from 34 to 94 nm, was observed. Low quality factors ͑Ͻ680͒ obtained from the mechanical resonance is attributed to the layered structural nature of BNNT.
