The international conference on theoretical, experimental and numerical studies of nucleation and growth of crystals and thin films (http://mgctf.ru) will take place at Saint-Petersburg Scientific Center of the Russian Academy of Sciences on July 1鈥�5, 2019. The topics include the fundamental problems of phase transitions, nonlinear and collective phenomena during crystal growth, physics, chemistry, mechanics of crystal surfaces, lattice defects. The works concerning wide-bandgap semiconductors are especially welcome. Participants can give a plenary lecture (35 minutes), an oral presentation (20 minutes) or a poster. The deadline for submitting abstracts (up to 3,500 characters with spaces) is April 1, 2019. Full-length articles based on the conference materials will be published in a special issue of the journal 鈥淧hysics of the Solid State鈥� (impact factor 0.925).
