摘要: We fabricate and explore the resonance characteristics of self-supporting thin film based metallic nanocantilever systems. Nanocantilevers Au Ag are fabricated from (polycrystalline) films (~100 nm) grown via a surfactant mediated process. Focused ion beam assisted milling manipulation techniques used to nanocantilevers. The cantilevers investigated by piezoelectric base excitation method frequencies their first modes determined digitally processing analysing scanning electron microscopy images captured during study. nanocantilevers observed deviate Euler–Bernoulli description. suggest polynomial expression describe peculiar dimensional dependence frequency mechanically vibrating nanocantilever, where zeroth order term in represents an like form. also demonstrate fabrication measurement technique for elastically coupled system analysis its vibration means analogous mass–spring system.
