Graphical Abstract
  • optical microscopy on the surface of the smectic A, nematic and isotropic phases. The properties of this periodic structure are similar to the charged liquid helium surface and can be explained by nonlinear electrostatic instabilities previously described. Keywords: focal conic domains; free boundary
  • example, AFM, light reflection, high-resolution microscopy, X-ray reflection, transmission electron microscopy (TEM), etc. We have applied the four most popular microscopy tools: polarized optical microscopy, ISSA, AFM, and SNOM and compared experimental images of focal conic domains (FCDs) [11][12][13
  • microscopy and ISSA images with a previous paper [15] shows complete similarity with our results. Therefore, we can conclude that classical focal conic domains on the SmA phase free surface were observed. The model of the FCD structure is shown in Figure 10. The FCDs are ordered in one-dimensional periodic

Graphical Abstract
  • boundary. The capabilities of this new experimental method, as applied for liquid crystal free boundaries, are discussed. The formation of focal conic domain structures at the smectic-A–air free boundary was detected and studied. Keywords: focal conic domains; free boundary; liquid crystals
  • classic material for observation of focal conic domains (FCDs). FCDs appear when two competing boundary conditions take place at a boundary. In our case, the liquid crystal has strong boundary conditions on the solid substrate and the director is oriented parallel to the substrate. On the free boundary
