Measurements of the longitudinal magnetoconductivity a== of the nondegenerate two-dimensional system of electrons on the surface of liquid helium are presented for magnetic fields up to 22 T in the temperature range 0.4 K < T < 2.1 K. For temperatures above 1.6 K our experimental results axe in good

โฆ Synopsis
Measurements of the magnetoresistivity of Pn: of a 2DEG on liquid helium below lK show the influence of many-body effects on the electron-ripplon scattering in the extreme quantum limit.

We present electrical transport and photoluminecence results for high mobility p-type GaAs/(AIGa)As systems. We observe transitions into an insulating state characterized by an activation energy and a threshold electrical field at a (density-dependent) Landau level filling factor. A new line also ap
Discussed are the details of the ground state of 2D electrons above liquid helium in the presence of high magnetic field normal to the helium surface. It is shown that the high magnetic field results in the appearance of a noticeable fraction of autolocalized electrons so that both for ripplon and g
