Abstract:

Research on high temperature ferroelectric storage media led to the discovery of a class of ferroelectric materials which require a minimum threshold field for switching. This property was heretofore not observed in ordinary ferroelectrics and compares with similar properties found in ferrite cores. Work was conducted essentially to exploit the phenomenon of ferrielectricity for application in computer logical devices. The feasibility of preparing capacitors having a ferrielectric as a dielectric was investigated. Limiting electrical parameters of the device were determined. Finally, a novel non-destructive readout method was investigated using electromagnetic interferometer techniques. With the experimental device constructed, the best signalto-noise ratio obtained was 61. It is possible to obtain millions of readouts from a ferroelectric capacitor without destroying the state of polarization of the ferroelectric capacitor. Author
