Abstract:Bound states of composite particles in single and double quantum wells are studied. The spectrum and polarizability of an indirect trion and an indirect D ? center (a negatively charged donor) in crossed electric and magnetic fields are found. Bound dielectron states in a single quantum well are studied. The possibility of observing a dielectron experimentally by the magnetic-dipole absorption of electromagnetic waves is pointed out.
