Patterning of liquid crystal textures

 

Povzetek / Abstract:

The flowing nature of liquid crystals allows self-organization and reconfigurability, and their anisotropy is ideal for making patterns that respond to and modulate light. Controlling the patterns made by liquid crystals is thus a forefront of research, not only for displays, but in basic research as well.  I will present various ways of producing and controlling patterns in liquid crystals, including colloidal inclusions, creation of chiral solitons, topographical patterning and photoalignment procedures. I will further discuss the topological nature of produced patterns and present the recently published results of micropatterning with air trapped in etched holes.
