Tip Calibration Standard And Method For Tip Calibration
US Patent:
6720553, Apr 13, 2004
Filed:
Jan 17, 2003
Appl. No.:
10/346630
Inventors:
Dawn Bonnell - West Chester PA
Alan T. Johnson - Philadelphia PA
Sergei V. Kalinin - Knoxville TN
Marcus Freitag - Mohegan Lake NY

Assignee:
Trustees of the University of Pennsylvania - Philadelphia PA
International Classification:
H01J 3720
US Classification:
2502521, 250306, 250307
Abstract:
The present invention is directed to a tip calibration standard for characterizing the geometric and electrostatic properties of the probe tips of scanning probe microscopes comprising a carbon nanotube mounted on a dielectric surface of a grounded, conductive substrate and connected to a contact mounted on the substrate. The present invention is also directed to methods for using such a tip calibration standard in calibrating probe tips, computing tip geometry and electrostatic data, and determining the convolution function so that tip-surface interaction effects can be separated from scanning probe microscope surface image data.

System And Methods For Detecting A Gaseous Analyte In A Gas
US Patent:
2010019, Jul 29, 2010
Filed:
Jan 25, 2010

International Classification:
G01N 33/551, G01N 29/02, B05D 5/12, H01L 41/22
US Classification:
436524, 73 2406, 427100, 216 13, 977742, 977843
Abstract:
Systems and methods for detecting a gaseous analyte utilize a micromechanical piezoelectric resonator having a functionalization layer configured to bind with the gaseous analyte. The functionalization layer may include a layer of carbon nanotubes affixed to the resonator and coated with biopolymers configured to bind with the gaseous analyte. The gaseous analyte may be detected by operating the micromechanical piezoelectric resonator and functionalization layer in the presence of the gas, detecting a change in the resonant frequency of the resonator, and determining the concentration of the gaseous analyte from the change in resonant frequency. Finally, the layer of carbon nanotubes may be grown on the piezoelectric resonator by depositing a catalyst on a piezoelectric structure, heating the piezoelectric structure and the catalyst to enhance the growth of the carbon nanotubes, and growing the carbon nanotubes at growth sites on the piezoelectric structure.
