Patent number: 12038667Abstract: Multi-state switchability is highly desirable in optoelectronic devices. For liquid crystal (LC) based devices, the stability of any configuration is achieved through a balance between imposed interactions and the LC's orientational elasticity. In most cases, the latter acts to resist deformation. By combining surface topography and chemical patterning, provided here are the effects of saddle-splay orientational elasticity, a property that, despite being intrinsic to all LCs, is routinely suppressed. Utilizing theory and continuum elastic calculations, provided here are example conditions for which, even using generic, achiral LC materials, spontaneously broken surface symmetries develop. Also provided are multi-stable devices in which a weak, but directional, applied field switches between spontaneously-polar surface state domains. The disclosed approach is useful in low-field and fast-switching optoelectronic devices, beyond those attainable by current technologies.Type: GrantFiled: March 4, 2020Date of Patent: July 16, 2024Assignees: THE TRUSTEES OF THE UNIVERSITY OF PENNSYLVANIA, TRUSTEES OF TUFTS COLLEGE, SHEFFIELD HALLAM UNIVERSITYInventors: Shu Yang, Yu Xia, Timothy J.
