“…Figure (b) shows SEM image of a single CNW grown at the tip of W needle. As it was shown previously, the CNW deposited under influence of focused electron beam in the chamber of SEM have amorphous structure with 2200 kg m −3 density. Therefore, Young's modulus of the studied nanowhiskers could be evaluated as E = 1.3 ± 0.1 × 10 10 Pa. For comparison, Young's modulus of single‐wall nanotubes, diamond and graphite are in the order of 1.2 × 10 12 , 8 × 10 11 , and 1.5 × 10 11 Pa, respectively.…”

“…It is worth noting that the presence of residual pressure and hydrocarbons in the SEM chamber makes it possible the formation of nanowhiskers under the influence of a focused electron beam (FEB). Interaction of the FEB with hydrocarbons of the precursor gas leads to carbon layer‐by‐layer deposition at exposed point . As a result, growth of CNW with a typical length of 2–4 µm and a diameter of about 100 nm occurs.…”

“…The development of nanofabrication techniques led to the creation of a variety of nanoelectromechanical sensors, including nanomechanical oscillators (NMO) . Due to submicron sizes these resonators have low weight and high resonance frequency, which provides high sensitivity and allows to weigh micro‐ and nanoobjects.…”

Nano‐mechanical oscillator (NMO) based on amorphous carbon nanowhisker (CNW) with nanotraps for resonant weighting of nanoparticles in range of mass (10−14–10−15) g is presented. NMO with nanotraps is fabricated on the top of tungsten tip using focused electron beam technique. For resonant weighting the gold nanospheres are captured under the exposure of an electron beam by nanotraps locate on the top of CNW. Jump of gold nanoparticle to the nanotrap and oscillations of CNW are visualized using scanning electron microscope (SEM). The NMO amplitude‐frequency characteristics are calculated via automated numerical analysis of the sequence of SEM images obtained during the oscillations frequency sweeping. In order to calibrate the resonance mass detector based on CNW with nanotrap the gold nanosphere with diameter of (170 ± 5) nm and mass of (49.6 ± 9.2) × 10−15 g is weighed in vacuum.

Nanomechanical oscillators based on amorphous carbon whiskers, localized on the top of tungsten tip were fabricated and investigated. The whiskers were grown in the scanning electron microscope chamber using focused electron beam technique. Oscillation trajectories and amplitude-frequency characteristic of the oscillator were visualized at low and ambient pressure using a scanning electron microscope and a confocal laser-scanning microscope, respectively. We experimentally show that at ambient pressure, the resonant frequency decreases significantly but the Q-factor of the oscillator unexpectedly increases with respect to experimental data acquired at low pressure. The explanation was provided taking into account the role of thin water layer absorbed on the whisker from atmosphere. The model of the coupled oscillators is considered.

Nanomechanical resonators provide a versatile platform for nanoscale mass sensing and force microscopy, as well as for enhancing light‐matter interaction offering unique functionality for optomechanical applications. In this way, discovering new approaches for coupling light with the mechanical degrees of freedom opens the strong desire paths for further developing of nanomechanical technology. Here, the parametric optothermal modulation of hybrid nanomechanical systems consisting of carbon nanowire with a silicon nanoparticle on its top, is reported. The mechanism of the modulation is based on the periodic optical heating of the nanowire and further modulation of the elasticity parameters. Utilizing the silicon nanoparticle provides additional functionality owing to optical absorption enhanced with Mie resonance and the unique feature of optical Raman thermometry enabling optical monitoring of local temperature. It is shown that the parametric mechanism of modulation allows for a significant increase of the optomechanical coupling strength.
