Title of the Boeing T-43A Flight Manual. An aircraft flight manual (AFM) is a paper book or electronic information set containing information required to operate an aircraft of certain type or particular aircraft of that type (each AFM is tailored for a specific aircraft, though aircraft of the same type naturally have very similar AFMs).
Showing an AFM artifact arising from a tip with a high radius of curvature with respect to the feature that is to be visualized AFM artifact, steep sample topography. AFM images can also be affected by nonlinearity, hysteresis, [43] and creep of the piezoelectric material and cross-talk between the x, y, z axes that may require software ...
nc-AFM was the first form of AFM to achieve true atomic resolution images, rather than averaging over multiple contacts, both on non-reactive and reactive surfaces. [ 32 ] nc-AFM was the first form of microscopy to achieve subatomic resolution images, initially on tip atoms [ 42 ] and later on single iron adatoms on copper.
In AFM, feedback loops control the operation of the microscope by keeping a fixed value a parameter of the tip's oscillation. [11] If the main feedback loop operates with the amplitude, the AFM mode is called amplitude modulation (AM). If it operates with the frequency shift, the AFM mode is called frequency modulation (FM).
Topographic (left) and current (right) maps collected with CAFM on a polycrystalline HfO 2 stack. The images show very good spatial correlation. In microscopy, conductive atomic force microscopy (C-AFM) or current sensing atomic force microscopy (CS-AFM) is a mode in atomic force microscopy (AFM) that simultaneously measures the topography of a material and the electric current flow at the ...
This type of AFM operation is referred to as the force mode. With this probe, one can study interactions between various surfaces and probe particles in the sphere-plane geometry . It is also possible to study forces between colloidal particles by attaching another particle to the substrate and perform the measurement in the sphere-sphere ...
In AFM-IR these contact resonances are automatically excited every time an infrared pulse is absorbed by the sample. So the AFM-IR technique can measure the infrared absorption by the amplitude of the cantilever oscillation response and the mechanical properties of the sample via the contact resonance frequency and quality factor.
