Observation of Higher Order Facets on 3He Crystals
Abstract
Faceting has been observed on 3He crystals investigated with a low-temperature Fabry-Perot interferometer. Nine types of facets were clearly identified during growth of a bcc-3He single crystal at a temperature of 0.55 mK, while previously only three types of facets have been seen. Due to the weak coupling between the liquid-solid interface and the solid lattice in 3He the facets are too small to be observed in equilibrium. The number of facets observed in our experimental conditions is consistent with the theory of dynamic roughening.
