Abstract

The time-of-flight method has been used to study the transport of indirect excitons in AlAs/GaAs CQW structures at T ≥ 350 mK and B ≤ 14 T. A large increase of the exciton diffusivity is observed at high magnetic fields and low temperatures, when exciton superfluidity is expected to occur.
