摘要:
Electroactive microelectromechanical device of the Artificial Hair Cell type, comprising a moving cilium structure including a substrate (11, 12; 42) and a cantilever (18; 48), partly or entirely in.piezoelectric material, subject to bending or deformation following the action of a force and/or an applied voltage (V app1 ), said cantilever (18; 48) comprising a multilayer (13, 14a, 14b, 16) inducing a stress-driven geometry in which a portion (19) of said cantilever (18; 48) lies outside of a plane defined by the substrate (11, 12; 42). According to the invention said cantilever (18; 48) is associated to a piezoresistive element, in particular of piezoresistive material (15) configured to measure the bending or deformation of said cantilever (18; 48).
摘要:
The present invention is related to a probe for surface analysis by Atomic Force Microscopy. The tip body comprises at least a top portions formed of a rectangular ground plane, two trapezoidal side planes and two triangular side planes, with a straight line-shaped edge (11). One of the end points (18) of said edge serves as the tip point when the tip is held at an angle between the edge (11) and the surface to be scanned. The tip of the invention is obtainable by a process wherein a mold is produced by wet anisotropic etching through a rectangular or ellipse-shaped hardmask. The tip body is arranged on a cantilever, with the edge parallel or at an angle to the longitudinal direction of the cantilever. According to an embodiment in which the tip must be at an angle to said cantilever direction, the tip may have a rectangular top surface (20) instead of a straight line-shaped edge. The invention is equally related to a method for producing a probe according to the invention.

摘要:
A probe tip in an atomic force microscope is oscillated at a resonant frequency and at an amplitude setpoint and scanned across the surface of a sample at constant amplitude in intermittent contact with the sample. Changes in phase or in resonant frequency of the oscillating are measured to determine adhesion between the probe tip and the sample. The setpoint amplitude of oscillation of the probe is greater than 10 nm to assure that the energy in the probe lever arm is much higher than that lost in each cycle by the probe striking the sample surface so that the probe tip does not stick to the sample surface. Force dependent sample characteristics are determined by comparing data obtained at different tapping amplitude setpoints.
