  • Publication number: 20090139313
    Abstract: A scanning probe microscope and method for using the same are disclosed. The scanning probe microscope includes a probe, an electromechanical actuator that moves the sample relative to the probe, an external interface, and a controller. The probe has a tip that moves in response to an interaction between the tip and a local characteristic of a sample. The external interface provides a connection between the scanning probe microscope and a device external to the scanning probe microscope. The controller records scanning probe microscope data measurements, each scanning probe microscope data measurement including a location of the probe in the three dimensions and a label that uniquely identifies that measurement and allows that measurement to be correlated with data generated by a device that is external to the scanning probe microscope. The unique label could include the time at which the data measurement was made.

  • Publication number: 20090139314
    Abstract: The true roughness of highly granular perpendicular media is measured by forming an inverse replica of the surface of the media. The invention enables AFM measurements of granular media valley depth to more consistently predict the corrosion performance of the media. A liquid resist is used to first replicate the media topography and form the inverse replica. The narrow valleys in the original media are precisely modeled as sharp peaks on the replica. The height of the peaks are readily measured with an AFM tip. The resulting image is a negative of the original surface.

  • Publication number: 20090139315
    Abstract: A method, a system and a computer readable medium for dynamic mode AFM amplitude versus distance curve acquisition. In an embodiment, a constant force feedback mechanism is enabled prior to the first time an AFM probe tip contacts a sample. The feedback mechanism setpoint is iteratively reduced while at least phase and amplitude of the probe tip are recorded as a function of the relative z-height of a cantilever coupled to the probe tip. The feedback mechanism setpoint may be repeatedly swept between upper and lower bounds to average out drift between the cantilever and sample. Upon detecting a threshold, an absolute tip-to-sample distance is determined and correlated to the relative z-heights. The amplitude and phase data recorded prior to tip-sample contact is then determined as a function of absolute tip-to-sample distance.

  • Patent number: 7542872
    Abstract: A form measuring instrument measures a form of a surface of an object to be measured using a contact to follow the surface. A pseudo-measurement point acquirer acquires positional coordinates of the reference point of the contact as pseudo-measurement points when the contact touches the object at a plurality of locations. A normal vector generator estimates a surface or line along the pseudo-measurement points from the pseudo-measurement points to calculate normal vectors extending from the pseudo-measurement points to the surface or line. A contact model locator locates contact models which specify the surface form of the contact so as to coincide the pseudo-measurement points with reference points of the contact models and so as to coincide attitudes of the contact on measurement with attitudes of the contact models. A measurement point calculator calculates cross points as measurement points, at which the normal vectors cross the surfaces of the located contact models.

  • Publication number: 20090114001
    Abstract: Roughness is added to the surface of a bluff body in a relative motion with respect to a fluid. The amount, size, and distribution of roughness on the body surface is controlled passively or actively to modify the flow around the body and subsequently the Vortex Induced Forces and Motion (VIFM). The added roughness, when designed and implemented appropriately, affects in a predetermined way the boundary layer, the separation of the boundary layer, the level of turbulence, the wake, the drag and lift forces, and consequently the Vortex Induced Motion (VIM), and the fluid-structure interaction. The goal of surface roughness control is to increase Vortex Induced Forces and Motion. Enhancement is needed in such applications as harnessing of clean and renewable energy from ocean/river currents using the ocean energy converter VIVACE (Vortex Induced Vibration for Aquatic Clean Energy).

  • Patent number: 7526949
    Abstract: A high-resolution scanning probe microscope using a coherent dual-tip probe comprises two single-atom protrusions on a single crystal metal wire. As the dual-tip probe scans across the surface of a sample material under an electrical bias, an interferenced electron wave function formed by two protruding atoms interacts with electron wave functions of the sample surface. Such an interferenced wave function has a distinctive pattern of electron wave density as high as four times that of a single-atom tip. A more distinctive microscopic image of the sample surface is therefore generated. The resolution of the dual-tip scanning probe microscopic image is also higher than that obtained by a single-tip probe because the interferenced electron wave function provides a confined and densely distributed interactive region.

  • Publication number: 20090031792
    Abstract: A method of producing a probe device for a metrology instrument such as an AFM includes providing a substrate having front and back surfaces and then forming an array of tip height structures on the first surface of the substrate, the structures having varying depths corresponding to selectable tip heights. The back surface of the substrate is etched until a thickness of the substrate substantially corresponds to a selected tip height, preferably by monitoring this etch visually and/or monitoring the etch rate. The tips are patterned from the front side of the wafer relative to fixed ends of the cantilevers, and then etched using an anisotropic etch. As a result, probe devices having sharp tips and short cantilevers exhibit fundamental resonant frequencies greater than 700 kHz or more.

  • Publication number: 20090031793
    Abstract: A method of assessing the surface roughness of an object includes directing gas supplied at a constant pressure through a control orifice and subsequently to a measurement nozzle adjacent to and spaced from a surface of the object, with subsequent escape of the gas to the atmosphere. The object is moved past the measurement nozzle and the resultant back pressure of the gas upstream of the measurement nozzle and downstream of the control nozzle is measured to provide a back pressure signal. The frequency content of the back pressure signal is examined to thereby obtain an assessment of the surface roughness of the object.
