Abstract:In this study, we demonstrated the evaluation of the device parameters, such as the cell thickness d, pretilt angles at the top and bottom substrates θ0 and θd, and twist angle φt for the guest-host (GH)-type electrically controlled birefringence (ECB) and twisted nematic (TN) modes, using the renormalized transmission ellipsometry (RTE). In the proposed technique, the extended Cauchy equation and the extinction coefficients for the ordinary and extraordinary rays based on the three Gaussian functions were emp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
