| We investigated current-voltage and photocurrent-voltage characteristics of a double-barrier resonant tunneling structure based on AlGaAs. To explain the observed "double-step" feature of the characteristics, we have proposed a mechanism including a multiple phonon emission of an electron dwelling in the quantum well. |
