Abstract

The phenomenon generally called the «dip-effect » in conduction of 2D electrons at a helium film on a rough substrate is discussed. A special case of the dip-effect appearing in moving 2D electrons along the helium film covering a periodically corrugated substrate is considered. Arguments for extending the outlined scenario to 2D electrons above the substrates with arbitrary corrugation on difficulties of this approach are presented.
