The present volume continues the tradition of previous issues in covering all the main divisions in the science of crystal growth: growth from vapor, solution, and melt. At the same time, it reflects the recent tendency to more detailed research on solid -state crystal lization. In compiling the collection, preference has been given to papers that not only present novel scientific results but also contain surveys of the published data, although certain of the papers are purely original ones and some are purely of review character. The need for these surveys is dictated by at least two...

The present volume continues the tradition of the preceding volumes. covering a wide range of crystal growth problems and treating aspects of critical importance for crystalliza tion. Changes in this field of knowledge have. however, changed the criteria for selection of papers for inclusion in this series. The increasing role of crystals in science and technology is even more apparent today. The study and utilization of these highly perfect objects of nature considerably facilitates progress in the physics and chemistry of solids. quantum electronics, optics, microelectron ics, and other...
