Investigating the effect of HK friction model input parameters on the force and critical time in gold nanoparticle manipulation

In the macro scale, surface forces such as friction and adhesion are of little importance and can be ignored. But in the micro/nano world, these forces are of great importance. For this purpose, in order to simulate the manipulation of nanoparticles based on the atomic force microscope, various friction models can be used, including the HK friction model. Accurate calculation of force and critical time, respectively, in order not to damage the particle and to reach the target point in the manipulation process is important and necessary. In this research, data were collected using the Taguchi test design method in three levels. The amount of force and critical time were calculated for each test. Then, with the help of analysis using the signal-to-noise ratio method, to investigate the effect of the input parameters of the HK friction model including, , ,B and M The reduction of the critical force and the increase of the critical time in mamipulation the gold nanoparticle with a radius of 50 nm on the silicon oxide substrate have been discussed. Based on the obtained results, parameter B as the first parameter and M as the second parameter with the lowest signal-to-noise ratio on reducing the critical force and with the highest signal-to-noise ratio at the critical time at level 3 with values of -1.869 and -0.3419.
