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