Abstract
X-ray-scattering data from chiral smectic-A liquid crystals under an a pplied electric field have been analyzed to investigate the layer-buck ling instability. A quantitative description of the scattering data at all values of the field is obtained via calculation of the minimal-en ergy layer displacement profiles determined from the continuum smectic free energy. From this analysis the real-space layer-buckling profile s are determined, revealing a sinusoid to soliton evolution with incre asing field.
