Bilayer Liquid Crystal and Freedericksz Instability

Abstract : Micro Abstract Liquid crystals are best known for their extensive applications, among many others, in flat display technology. The underlying mechanism is an electro-mechanical coupled phenomenon, followed by an electric field driven instability. This is also known as Freedericksz Transition (FT), where the system evolves with a new stable bifurcated configuration. In this work, through a mixed analytical/numerical study, we present the strong influences of bilayer structure and material constants on the FT.
