Abstract: Methods and apparatuses are provided for automatically controlling and stabilizing aspects of a scanning probe microscope (SPM), such as an atomic force microscope (AFM), using Peak Force Tapping (PFT) Mode. In an embodiment, a controller automatically controls periodic motion of a probe relative to a sample in response to a substantially instantaneous force determined and automatically controls a gain in a feedback loop. A gain control circuit automatically tunes a gain based on separation distances between a probe and a sample to facilitate stability. Accordingly, instability onset is quickly and accurately determined during scanning, thereby eliminating the need of expert user tuning of gains during operation.

Abstract: A method of operating a metrology instrument includes generating relative motion between a probe and a sample at a scan frequency using an actuator. The method also includes detecting motion of the actuator using a position sensor that exhibits noise in the detected motion, and controlling the position of the actuator using a feedback loop and a feed forward algorithm. In this embodiment, the controlling step attenuates noise in the actuator position compared to noise exhibited by the position sensor in a bandwidth of about seven times the scan frequency. Scan frequencies up to a third of the first scanner resonance frequency or greater than 300 Hz are possible.

Abstract: Reversible phase transitions of exceptional magnitude may be induced in correlated metal oxides by altering their chemical compositions through reversible introduction of dopant ions and electronic carriers into the correlated metal oxides. One or more catalyst electrodes may be deposited onto a surface of a film of a correlated metal oxide such as a perovskite or a transition metal oxide. Dopant ions and electronic carriers may be electrochemically introduced into the catalyst-deposited correlated metal oxide, for example by annealing the catalyst-deposited film of correlated metal oxide in a chamber containing the dopant molecules. In this way, a reversible phase transition of about five to eight orders of magnitude may be induced.
