Automated FM-AFM Feedback Tuning

ثبت نشده
چکیده

FM-AFM is an extremely powerful and versatile imaging technique capable of atomic resolution imaging in vacuum, air or liquid. However, obtaining such results in practice currently requires tedious and time consuming manual tuning of many feedback parameters by trial and error. We present a recently developed algorithm for automated tuning of FM-AFM feedback parameters. The algorithm optimizes the performance of FM-AFM and makes it significantly simpler to operate.

Simulations of the Frequency Modulated - Atomic Force Microscope (FM-AFM) Nonlinear Control System

The Frequency Modulated Atomic Force Microscope (FM-AFM) is a powerful tool to perform surface investigation with true atomic resolution. The control system of the FM-AFM must keep constant both the frequency and amplitude of oscillation of the microcantilever during the scanning process of the sample. However, tip and sample interaction forces cause modulations in the microcantilever motion. A...

Spatial horizons in amplitude and frequency modulation atomic force microscopy.

In dynamic atomic force microscopy (AFM) the cantilever is vibrated and its dynamics are monitored to probe the sample with nanoscale and atomic resolution. Amplitude and frequency modulation atomic force microscopy (AM-AFM and FM-AFM) have established themselves as the most powerful methods in the field. Nevertheless, it is still debatable whether one or the other technique is preferred in a g...

Dimensionality tuning of the electronic structure in Fe3Ga4 magnetic materials

This work reports on the dimensionality effects on the magnetic behavior of Fe3Ga4 compounds by means of magnetic susceptibility, electrical resistivity, and specific heat measurements. Our results show that reducing the Fe3Ga4 dimensionality, via nanowire shape, intriguingly modifies its electronic structure. In particular, the bulk system exhibits two transitions, a ferromagnetic (FM) transit...
