Abstract

Longitudinal optical (LO) phonon relaxation is investigated in a GaAs/AlGaAs triple barrier tunnel diode at strong perpendicular magnetic fields. We observe LO-phonon assisted tunneling to the ground state as well as to Landau level states. Maxima in the LO-phonon assisted tunnel peak are found each time the LO-phonon energy matches multiple of the Landau level spacing. Corresponding maxima as well as parity effects are found in the integral tunnel conductance. The results indicate enhancement of LO-phonon assisted inter Landau level transitions with increasing magnetic field.
