摘要：

Periodic modulations of the director inside the smectic layer were identified as being responsible for a stripe texture formation in free suspended films of the chiral smectic-C phase with the helix along the smectic layer normal, spontaneously unwound. Monotonous increase of the stripe periodicity with the increasing film thickness agrees with a theoretical model. A 2D modulated pattern observed in thick films was found to be related to the molecular chirality.
