摘要:

A unique one-dimensional system of linear electron chains on the liquid helium surface is realized experimentally for the first time. This system is created by using the distortion of the helium surface and covering the profiled dielectric substrate in a confining electric field holding electrons in the liquid channels being formed. The carrier mobility in linear electric chains is measured in the temperature interval 0.5–1.8Kin confining fields up to 1 kV/cm. It is shown that the electron mobility depends on the purity of the substrate surface. For clean substrates, the mobility increases with decreasing temperature in the entire investigated temperature range. The results of measurements are found to be in accord with the existing theory. ©1998 American Institute of Physics.

摘要:

The kinetics of growth and dissolution of a new phase during phase separation and homogenization of solid3He–4Hemixtures is studied experimentally. It is found that both these processes have different kinetics, while homogenization is ensured by an anomalously rapid transport of matter in the crystal. It is shown that the prevailing theories about diffusion processes in a quantum crystal cannot explain the obtained results. ©1998 American Institute of Physics.
