Spontaneous Periodic in-Layer Director Modulation in Tilted Chiral Smectics
Periodic director modulation within the smectic layers is observed as ID-stripe or 2D textures in free suspended films in SmC*, SmC*(A) and SmI*(A) phases in a temperature range where the helix along the smectic layer normal is spontaneously unwound. Temperature changes of the texture are significantly different in all three studied phases. Applied electric field affects the periodicity and the orientation of the stripe texture. Models of both 1D and 2D textures are presented.
