Charge relaxation in two-dimensional electron gas under quantum Hall effect conditions
Zhitenev N.B.
Time evolution of the Hall current in a two-dimensional electron gas with gate in the quantum Hall regime was studied. It was found that current rising time t\ is much less then the time ti of current redistribution over the whole sample. After t| net current flows in a narrow strip along the boundary. Value of net current does not change during the redistribution. An influence of non-equilibrium occupation of the edge channels on the value of rising time was observed.
