Growth Kinetics of 4He Quantum Crystals at a Temperature of 0.1–0.2 K
Abstract
The growth kinetics of 4He crystals nucleated in a metastable liquid at a supersaturation of up to 10mbar is studied in the temperature range 90–180 mK. An optical dilution cryostat is used to observe and film crystal growth. The boundary supersaturation separating the normal (slow) and abnormal (fast) growth regions is determined. The growth rate of crystal facets in the normal growth mode is measured. The kinetics of fast crystal growth is investigated as a function of supersaturation and temperature.
期刊介绍：
Journal of Experimental and Theoretical Physics is one of the most influential physics research journals. Originally based on Russia, this international journal now welcomes manuscripts from all countries in the English or Russian language. It publishes original papers on fundamental theoretical and experimental research in all fields of physics: from solids and liquids to elementary particles and astrophysics.
