Abstract

The short pulsed, tunable output from the Dutch free electron laser FELIX. coupled with a 45 T pulsed magnet has been used to measure the non-radiative decay rates between Landau levels in n-type InAs/GaSb quantum wells. The decay rate is 2 ps(-1) when the cyclotron resonance energy, E-CR = E-LO = 30 meV, and only slightly less, 0.8 ps(-1) when E-CR = 2E(LO) when the principal relaxation pathway is the emission of multiple longitudinal optical (LO) phonons, (C) 2001 Elsevier Science B.V.
