Abstract
We report results on the charging technique of liquid helium surface over rectangular electrodes and maximum sustainable electron density at temperatures above 1 K. Also, thermally activated escape of twodimensional electrons from the potential well has been studied as a function of various parameters like electrons density and temperature. Results provide insights into the charging process of the surface-state electrons and their stability parameters over these electrodes with AC capacitive coupling technique.
