Isotropic phase de-wetting of discotic liquid crystals on a surface patterned with alternating ~5-10 μm wide wetting and stripes results in the formation long narrow droplets. On slow cooling into columnar phase, crystal aligns such that columns lie either across or along stripes. However, if are wider and/or rate is too fast, defects appear. When there many defects, result complex zigzag wavy ...
