Crystal growth kinetics and the lateral habits of polyethylene crystals The lateral growth habits of lamellar crystals of polyethylene grown from solution can be typified in terms of the aspect ratio, r, which is the ratio of t... E Passaglia,F Khoury - 《Polymer》 被引量: 55发表: 1984年...
Gravity-related phenomena in crystal growth from solutions are reviewed in the first section of the paper. The second and third sections deal with solution growth experiments performed in space at high and low temperatures. The basis for conceiving these experiments is discussed and the experimental ...
Capillary solution evaporation theory is presented, which incorporates crystal formation near the mouth when supersaturation is reached; high evaporation rates and high solution concentrations can result in a transient state, where the crystal size pulsates....

The compounds Cu 2GeS 3, Cu 2SiS 3 and Cu 2SiSe 3 were dissolved in the ternary compound CuGe 2P 3. A modified Bridgman technique was used in the preparation, and good quality single crystals were grown for single phase samples. A complete solid solution for the system CuGe 2P 3-Cu...

Doping striations in silicon crystals grown by the Czochralski technique are examined. They are found to correspond closely to striations existing in solution-grown epitaxial layers of gallium arsenide and silicon. It is, therefore, concluded that the kinetic growth mechanisms which are active in solut...
