GDQEM Analysis for Free Vibration of V-shaped Atomic Force Microscope Cantilevers
V-shaped and triangular cantilevers are widely employed in atomic force microscope (AFM) imaging techniques due to their stability. For the design of vibration control systems of AFM cantilevers which utilize patched piezo actuators, obtaining an accurate system model is indispensable prior to acquiring the information related to natural modes. A general differential quadrature element method (...
متن کاملCalibration of rectangular atomic force microscope cantilevers
A method to determine the spring constant of a rectangular atomic force microscope cantilever is proposed that relies solely on the measurement of the resonant frequency and quality factor of the cantilever in fluid ~typically air!, and knowledge of its plan view dimensions. This method gives very good accuracy and improves upon the previous formulation by Sader et al. @Rev. Sci. Instrum. 66, 3...
متن کاملActuation and characterization of atomic force microscope cantilevers in fluids by acoustic radiation pressure
An actuation method for atomic force microscope ~AFM! cantilevers in fluids is reported. The radiation pressure generated by a focused acoustic transducer at radio frequency ~rf! ~100–300 MHz! exerts a localized force of controlled amplitude at a desired location on the AFM cantilever. This force can be used to measure the spring constant and other dynamic properties of the cantilever. Furtherm...
متن کاملParallel beam approximation for V-shaped atomic force, microscope cantilevers
Due to its simplicity, the parallel beam approximation (PBA) is commonly used in the analytical evaluation of the spring constant of V-shaped atomic force microscope (AFM) cantilevers. However, the point of contention regarding the validity of the PBA is as yet an unresolved issue, which has been exacerbated by some recent contradictory reports. In this paper, we present a detailed investigatio...
متن کاملHigh-frequency response of atomic-force microscope cantilevers
frequency response of atomic-force microscope cantilevers" (1997). Faculty Publications from the Department of Engineering Mechanics. Paper 2. Recent advances in atomic-force microscopy have moved beyond the original quasistatic implementation into a fully dynamic regime in which the atomic-force microscope cantilever is in contact with an insonified sample. The resulting dynamical system is co...
