Optical pertubation spectroscopy of modulation-doped InP/InGaAs heterostructures

摘要

Electronic structure and radiative recombination mechanisms in n-type modulation doped InP/InGaAs quantum structures are studied by means of a newly developed magnetooptical spectroscopy, based on optical detection of quantum oscillations via photoluminescence in a magnetic field. The advantages of the proposed method are demonstrated.
