    • We assume in the following that these modes are governed by thermal, rather than impurity, diffusion. The measured melting range of the smectic A phase (it was difficult to accurately measure the melting range of the multidomain solid phase) is (Formula presented) indicating a low impurity concentration. Moreover, addition of (Formula presented) to the samples produced no change in either growth morphologies or transition temperatures of the solid phase, indicating little sensitivity to the presence of impurities
