In situ observations of the growth behaviour of the {010} face of potassium hydrogen phthalate

The surface morphologies of the {010} face of potassium hydrogen phthalate crystals, growing in an aqueous solution, have been studied in situ by means of optical reflection microscopy. The observations have been recorded by means of a videosystem. Several phenomena have been investigated by this method, namely: spiral growth via high (10–250 nm) and low steps (2.8–10 nm), step acceleration near reentrant corners in step patterns, inclusion...
