Abstract
Using a Green’s-function approach, time evolution of the current after a pulse is applied to a double barrier is quantitatively calculated when an electron is incident with a fixed energy. Pulse switching causes the current to reverse from its peak (valley) value to its valley (peak) value. The relaxation time for current enhancement is longer than that for current reduction. Characteristic oscillations are found.Keywords
