【 摘 要 】

Nanomechanical oscillators (NMO) on the basis of crystalline W (tungsten) microwhiskers and amorphous C (carbon) nanowhiskers localized on the top of W tips are created and studied. Trajectories of single and coupled resonant oscillations are visualized, resonant frequencies and quality factor of NMO are determined. Trajectories of coupled resonant oscillations of NMO are simulated. Calculation results are qualitatively in agreement with the experimental data.
