Background: Noncontact atomic force microscopy (NC-AFM) now regularly produces atomic-resolution images on a wide range of surfaces, and has demonstrated the capability for atomic manipulation solely using chemical forces. Nonetheless, the role of th

The performance of organic semiconductor devices is strongly affected by the interface energetics at the junctions between the constituent materials. A large group of organic semiconductors consists of rodlike small molecules that crystallize upon de

Publikováno v: Nonlinear Dynamics. 86:2261-2277

Dynamical integrity of a noncontact AFM model with external feedback control is investigated to evaluate the effects of such local control procedure on the erosion of the basins of attraction of the system bounded solutions. Two-dimensional cross sec

Asymptotic analysis of a noncontact AFM microcantilever sensor with external feedback control

Publikováno v: Nonlinear Dynamics. 79:2675-2698

An external feedback control is inserted in a nonlinear continuum formulation of a noncontact AFM model. The aim of the feedback is to keep the system response to an operationally suitable one, thus allowing reliable measurement of the sample surface

Bifurcation, response scenarios and dynamic integrity in a single-mode model of noncontact atomic force microscopy

Autor: Giuseppe Rega, Valeria Settimi

Publikováno v: Nonlinear Dynamics. 73:101-123

The nonlinear dynamical behavior of a single-mode model of noncontact AFM is analyzed in terms of attractors robustness and basins integrity. The model considered for the analyses, proposed in (Hornstein and Gottlieb in Nonlinear Dyn. 54:93–122, 20
