Abstract:

A ferroelectric driven in a suitable circuit by a sinusoidal voltage will produce all harmonics of the driving field. A simple theory is developed to show that there is 180-deg phase shift for all even harmonics if the sign of the ferroelectric polarization is reversed, and no phase shift for odd numbered harmonics. Experimentally, single crystal triglycine sulfate conforms rather well to the simple theory, with the deviations at least qualitatively explicable. The 180-deg phase shift in the second harmonic has been suggested as a means of nondestructive readout for ferroelectric memory elements. The second harmonic amplitude appears ample for this purpose but is dependent on the crystal polarization history. It also appears that knowledge of the harmonic outputs of ferroelectrics under the influence of a driving field could be a valuable tool in the investigation of ferroelectrics and ferroelectricity.
