Visualization of complex oscillations of carbon nanowhiskers in SEM

The nanomechanical oscillators (NMO) in the form of carbon nanowhiskers (CNW) with oval cross-sections have been created and studied in scanning-electron microscope (SEM). For measurement of amplitude-frequency characteristics of CNWs the methods of machine vision were used. The CNWs and 2D framework carbon nanostructures were grown on tops of W needles with various radius of curvature in the range of (100-350) nm. Resonant oscillations along the big and the small sizes of CNW cross-section and rotational resonant modes of NMO were observed and analyzed.
