摘要：

A new approach for quantifying the elastic deformation behavior of one-dimensional nanostructures is presented by fitting the image profile measured using atomic force microscopy in contact mode along the entire length of a bridged/suspended nanobelt/nanowire/nanotube under different load forces. Consistently fitting the measured deformation profiles can uniquely determine if the measured data are best explained by either the clamped-clamped beam model or the free-free beam model without preassumption, and it eliminates the uncertainty in defining the central point of the suspended beam, thus, greatly increasing the precision and reliability of the measurements.
