  • Patent number: 8950010
    Abstract: The piezoelectric response of a sample (3) is measured by applying a scanning probe microscope, whose probe (2) is in contact with the sample (3). The probe is mounted to a cantilever (1) and an actuator (5) is driven by a feedback loop (7, 11, 12, 4) to oscillate at a resonance frequency f. An AC voltage with principally the same frequency f but with a phase (with respect to the oscillation) and/or amplitude varying periodically with a frequency fmod is applied to the probe for generating a piezoelectric response of the sample (3). A lock-in detector (20) measures the spectral components at the frequency fmod of the control signals (K, f) of the feedback loop. These components describe the piezoelectric response and can be recorded as output signals of the device. The method allows a reliable operation of the detector oscillator resonator (1) at its resonance frequency and provides a high sensitivity.

This methodology allows the independent measurement of resonance frequency, Q factor, and oscillation amplitude of a tip-surface contact area as a function of tip temperature, from which the thermal evolution of tip-surface spring constant and mechanical dissipation can be extracted. A heating protocol maintained a constant tip-surface contact area and constant contact force, thereby allowing for reproducible measurements and quantitative extraction of material properties including temperature dependence of indentation-based elastic and loss moduli.

  • Patent number: 8479309
    Abstract: Provided are methods and systems for high resolution imaging of a material immersed in liquid by scanning probe microscopy. The methods further relate to imaging a material submersed in liquid by tapping mode atomic force microscopy (AFM), wherein the AFM has a microfabricated AFM probe comprising a nanoneedle probe connected to a cantilever beam. The nanoneedle probe is immersed in the liquid, and the rest of the AFM probe, including the cantilever beam to which the nanoneedle probe is attached, remains outside the liquid. The cantilever is oscillated and the nanoneedle probe tip taps the material to image the material immersed in liquid. In an aspect, the material is supported on a shaped substrate to provide a spatially-varying immersion depth with specially defined regions for imaging by any of the methods and systems of the present invention.

  • Patent number: 8443461
    Abstract: Interatomic forces are measured with subatomic lateral resolution by in situ calibrated non-contact and passively thermal drift compensated atomic force microscopy in aqueous or generally liquidous environment; interatomic forces acting between distinct electronic orbitals of front-most tip atom and opposing sample atom can be quantitatively measured with subatomic lateral resolution. Calibration standard is a CaCO3-crystal, which undergoes a well defined pressure induced phase transition from the calcite to the aragonite crystal lattice structure providing an accurate independent force anchor point for the AFM's force versus distance curve. Furthermore, an independent actual tip-sample-distance d calibration is obtained by directly observing oscillatory (steric) solvation forces originating simply from packing effects of the liquid particles at very small tip-sample separations d.

  • Patent number: 8387161
    Abstract: An elongate probe (50) for use in probe microscopy comprises a module (51) provided between a probe tip (53) and a driver (52). In use the driver (52) applies oscillations to the module (51) which are transmitted by the module to the tip (53). With the probe tip (53) positioned close to the surface of a sample, any phase variance in the oscillation of the tip with respect to the driving oscillation is representative of an interaction between the tip and the sample surface. The elongate arrangement of the probe (50) is particularly beneficial when used to probe samples which require a liquid environment.

  • Patent number: 8347411
    Abstract: The scanning probe microscope has a primary control loop (7, 11, 12) for keeping the phase and/or amplitude of deflection at constant values as well as a secondary control loop (9) that e.g. keeps the frequency of the cantilever oscillation constant by applying a suitable DC voltage to the probe while, at the same time, a conservative AC excitation is applied thereto. By actively controlling the frequency with the first control loop (7, 11, 12) and subsequently controlling the DC voltage in order to keep the frequency constant, a fast system is created that allows to determine the contact potential difference or a related property of the sample (3) quickly.

  • Patent number: 8327460
    Abstract: The present invention allows simple and sensitive detection of microimpurities, microdefects, and corrosion starting points which may be present in a material. A probe microscope has a function to sense ions diffused from a specimen in a liquid. A probe is caused to scan over a predetermined range on a specimen. Then, the probe is fixed to a particular position in a liquid so as to set the distance between the specimen and the probe to a given value at which the microstructure of the specimen surface cannot be observed. Thereafter, one of the current between the probe and a counter electrode and the potential between the probe and a reference electrode is controlled, and the other of the current and potential which varies in accordance with the control is measured. Thus, ions diffused from the specimen are sensed.

  • Publication number: 20120304342
    Abstract: During a measurement in KFM mode of the surface potential of a material (P), a detection point (1) is arranged above a surface (S) of the material. Two piezoelectric actuators (2, 5) are used to monitor a mean distance of the detection point relative to the surface of the material and a mechanical oscillation of said point. During the measurement, a control voltage is applied between control electrodes (2a, 2b) of the piezoelectric actuator (2) which is dedicated to the mechanical oscillation of the detection point (1), said control voltage not having an alternative component to an angular frequency of electrical energisation of said detection point. A result of the KFM measurement is therefore separate from operating parameters such as a projection angle used to perform closed-loop control and a value of the angular frequency of electrical energisation. The invention thus provides absolute measurements of surface potentials.
