Logic Based Design Modeling with Shape Algebras

September 1, 1997
Author(s)
Scott Chase
A new method of describing designs by combining the paradigms of shape aglebras and predicate logic representations is presented. Representing shapes and spatial relations in logic provides a natural, intuitive mehtod of developing complete computer

Microwave Dielectric Characterization of Bulk Ferroelectrics

September 1, 1997
Author(s)
Claude Weil, Richard G. Geyer, L. Sengupta
We discuss the application of existing RF measurement techniques, including waveguide and mode-filtered cavity resonator methods, to the dielectric characterization of bulk high permitivity ferroelectrics at microwave frequencies.

Modulation of the Charge of a Single-Electron Transistor by Distant Defects

September 1, 1997
Author(s)
Neil M. Zimmerman, J. L. Cobb, Alan F. Clark
We have systematically measured two-level fluctuator [TLF] noise in a single-electron tunneling transistor. From the amplitude, duty cycle, and presence of intermediate states, we conclude that there is a cluster of triggered TLF's in this case. The

Optimizing the NIST Magnetic Imaging Reference Sample

September 1, 1997
Author(s)
Paul Rice, Stephen Russek, J Hoinville, Michael H. Kelley
We have further developed the NIST magnetic imaging reference sample to include a magnetic pattern which can indicate the magnetic polarity of a magnetic force microscope tip. Several samples cut from the same disk were measured with a single tip. We have
