Nanometer-scale structures with high aspect ratios such as nanowires and nanotubes
combine low mechanical dissipation with high resonance frequencies, making them ideal …

Dynamic range quantifies the linear operation regime available in nanomechanical
resonators. Nonlinearities dominate the response of flexural beams in the limit of very high …

Generating macroscopic nonclassical quantum states is a long-standing challenge in
physics. Anharmonic dynamics is an essential ingredient to generate these states, but for …

We demonstrate nonlinear coupling between two orthogonal flexural modes of single as-
grown GaAs nanowires. The resonant frequency of one mode can be shifted over many line …

We describe an optical transduction mechanism to measure the flexural mode vibrations of
vertically aligned nanowires on a flat substrate with high sensitivity, linearity, and ease of …

We investigate the sideband spectra of a driven nonlinear mode with its eigenfrequency
being modulated at a low frequency (< 1 kHz). This additional parametric modulation leads …

Nonlinearity in macroscopic mechanical systems may lead to abundant phenomena for
fundamental studies and potential applications. However, it is difficult to generate …

Micro-and nanoelectromechanical oscillators driven at or close to their resonance frequency
are used as sensors in many fields of science and technology. A decrease in the oscillator's …

We investigate the nonlinear mechanical properties of GaAs nanowires with anisotropic

Ultralong GaAs nanowires were grown by molecular beam epitaxy using the vapor–liquid–
solid method. In this ultralong regime we show the existence of two features concerning the …
