Publication number: 20090139315Abstract: 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.Type: ApplicationFiled: December 12, 2007Publication date: June 4, 2009Inventors: Chikuang Charles Wang, Biao Liu, Yuri S.

Patent number: 7526949Abstract: 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.Type: GrantFiled: July 21, 2006Date of Patent: May 5, 2009Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Jony Jiang Liu, Gerald J.

Publication number: 20090031793Abstract: 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.Type: ApplicationFiled: February 28, 2007Publication date: February 5, 2009Inventors: Philip Koshy, Francois Yacoub

Publication number: 20090025465Abstract: A miniaturized spring element is intended to be particularly suitable for use as a beam probe or cantilever for detecting atomic or molecular forces, in particular in an atomic force microscope, and, to this end, is intended to make it possible to detect its deflection in a particularly reliable manner and with high resolution. For this purpose, the spring element contains a basic body which is formed from a matrix containing embedded nanoparticles or defects. The spring element is produced using the principle of local deposition with focused energetic particles or electromagnetic waves or by pyrolytically induced deposition.Type: ApplicationFiled: August 1, 2008Publication date: January 29, 2009Applicants: NANOSCALE SYSTEMS, NANOSS GMBH, JOHAN WOLFGANG GOETHE-UNIVERSITäTInventors: Alexander Kaya, Michael Huth

Publication number: 20090025464Abstract: A surface-roughness/contour measuring apparatus (1) comprises: a stylus orientation changing part (9) by which a rotatable support part (62, 64, 71a, 71b) for supporting a cantilever (7) in such a manner as to be rotatable on a rotational axis extending in a direction perpendicular to the longitudinal direction of the cantilever (7) is rotated about the longitudinal direction of the cantilever (7), thereby changing the orientation of a stylus (11) provided at a forward end of the cantilever (7); and a balancing member (63) which balances the weight of the cantilever (7) about the rotational axis in order to eliminate the effect of the gravitational force acting on the cantilever (7) rotating with the rotation of the rotatable support part (62, 64, 71a, 71b).Type: ApplicationFiled: May 29, 2006Publication date: January 29, 2009Inventor: Masafumi Ishii

Patent number: 7481099Abstract: A tubular piezoelectric device which is cylindrically shaped and has cutouts in one end portion. The one end portion of the piezoelectric device is mounted to a mount stage made of a material that has a different coefficient of thermal expansion from the material of the piezoelectric device. Electrodes are mounted on the piezoelectric body. The micromotion device produces micromotions of the other end portion of the piezoelectric body. The cutouts produce elastic deformation which absorbs differences in the amount of deformation between the piezoelectric body and the mount stage caused by temperature variations.Type: GrantFiled: December 18, 2006Date of Patent: January 27, 2009Assignee: JEOL Ltd.Inventor: Takaaki Amakusa

Patent number: 7478552Abstract: A method of operating a probe based instrument includes a light source that generates and directs a beam of light towards a probe of the instrument to detect a property of probe deflection. The method automatically adjusts the position of the light beam on the probe based on movement of the probe by a Z actuator so as to eliminate apparent parasitic deflection of the probe. A light source assembly for detecting deflection of a probe preferably includes a base, a tip/tilt stage mounted on the base and a light source supported by the tip/tilt stage. The tip/tilt stage includes at least one electrically actuated fine adjustment actuator that controls the tip/tilt stage, preferably independently of movement of the AFM scanner used to move the probe.Type: GrantFiled: March 21, 2006Date of Patent: January 20, 2009Assignee: Veeco Instruments Inc.Inventors: Doug Gotthard, Ben Ohler
