Two Liquids Wetting and Low Hysteresis Electrowetting on Dielectric Applications [PDF]

Langmuir, 2009
This study focuses on electrowetting using two immmiscible liquids on a dielectric coating. It is demonstrated that low contact angle of oil on the hydrophobic surfaces is a key parameter to obtain a low hysteresis system, below 2 degrees . On the basis of these results, three aspects of the wetting properties have been studied: the influence of the ...

Modelling of dielectric hysteresis loops in ferroelectric semiconductors with charged defects [PDF]

Journal of Physics: Condensed Matter, 2004
We have proposed the phenomenological description of dielectric hysteresis loops in ferroelectric semiconductors with charged defects and prevailing extrinsic conductivity. Exactly we have modified Landau-Ginsburg approach and shown that the macroscopic state of the aforementioned inhomogeneous system can be described by three coupled equations for ...
