Depolarization Phenomenon in Ferroelectric Devices
Rockville MD April 2010- Present

" Proposed Phenomenon of Depolarization in Ferroelectric devices:
"Depolarization Fields in Thin Ferroelectric Films", R. R. Mehta, B. D. Silverman and J. T. Jacobas, J. Appl. Phys., Vol44, No. 8, 1973. (Part of this paper was presented at Physical Society meeting in San Francisco, 1973)."Has been cited extensively in the scientific literature science 1997

" Recently it has been cited by Japanese scientist Yukio Watanabe in March 2010:
"Proper Permittivity for Depolarization Field and Its Implication to Universal Instability of Insulating Ferroelectric: A Note: Physical Society of Japan Vol. 79, No. 3, March, 2010, 034713 by Yukio Watanabe". In this publication he asserts that that in very large numbers of scientific publications this formula (equation 1 of 1973 publication has been used for calculation of Depolarization. He christens the formula derived in publication in 1973 (equation 1) as "Mehta's Formula".

Currently involved in exploring the relationship of these Depolarization Fields to the 2nd law of Thermodynamics.
