In this paper, the pull-in instability of electrostatically actuated nanotweezers considering the dispersion forces is studied using distributed and lumped parameter models. By analogy to nanoswitches, closed-form solutions are obtained for electrostatic nanotweezers. The distributed and lumped parameter modeling of the tweezer result, respectively, in two coupled nonlinear boundary value problems and two coupled nonlinear equations, which are solved numerically in the cases of electrostatic microtweezers, freestanding nanotweezers, and electrostatic nanotweezers. In each case, analytical and numerical solutions are obtained and compared with those of the corresponding switch. In addition, the results of the distributed and lumped parameter models are compared. The detachment length and minimum initial gap of nanotweezers are determined. 相似文献

The (n,p) and (n,2n) reaction cross sections on natural Ti and Mo targets have been measured forE
n
=14.73±0.05 MeV neutrons using the activation technique. The induced gamma-ray activities of the irradiated samples and their
monitor foils were measured by using an HPGe detector. The cross sections were compared with previous results. The experimental
uncertainties are between 3% and 8% in most cases. 相似文献

In this note the basis of the Kaluza-Klein theory is examined critically and it is pointed out that the five-dimensional version can’t work in the way that was originally intended. The reason why the problem was not noted originally is elucidated. 相似文献
