Abstract
We report on growth and magnetooptical studies of two types of novel C dTe/CdMgTe quantum well structures having a precisely controlled gradi ng of either the quantum well width or the donor concentration in a di rection perpendicular to the growth axis. The presence of two-dimensio nal electron gas of varying concentration produced by the graded modul ation doping was evidenced by observation of negatively charged excito n-electron complexes (X-).
