摘要：

Inelastic resonant tunnel spectroscopy is used to directly probe the density of states of two-dimensional magnetopolarons in a GaAs quantum well over a wide range of energies and magnetic fields. In agreement with theory, Landau levels are found to be drastically renormalized near degeneracies between the longitudinal-optic-phonon and cyclotron energies. © 1990 The American Physical Society.
