    Abstract

    The mobility of carriers in a quasi-one-dimensional electron system over liquid helium has been measured at temperatures of 0.5–1.5 K in pressing electric fields up to 2.5 kV/cm. The system is realized with using the optical diffraction grating situated at height H over liquid helium level. It is shown that electron mobility is dependent on the value H and significantly lower than that of over bulk helium. The mobility increases under lowering temperature and then decreases passing maximum. The behavior of the mobility is attributed with the localization of electrons in a quasi-one-dimensional system.
