| Abstract | The transverse electrooptic effect was observed in solution-coated lead zirconate thin films. The electric-field-induced birefringent shift exhibited a characteristic response which differed from the normal butterfly-like loops for ferroelectric materials. The observed unique response in lead zirconate thin films was related to their antiferroelectric nature and the electric-field-induced antiferroelectric-ferroelectric phase transition. Under an appropriate static bias electric field, the material possesses two distinguishable birefringent states associated with the two remanent polarization states of the material. The thin films were also found to acquire a permanent birefringence once a sufficiently high electric field was applied to the virgin materials. Two types of mechanisms are proposed for utilizing the antiferroelectric thin films for optical memory in optoelectronic devices. The first makes use of the permanent orientation of the material induced by an initial electric field. The second involves the switching between the two distinguishable birefringent states of the material under a bias field with electric pulses.< |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
