Abstract
The photoluminescence (PL) of InP/In0.53Ga0.47 As superlattices doped with Si in the inner barriers was studied. In magnetic fields 0-18 T applied par allel to the growth direction the PL develops a Landau level structure. An analysis of the Landau level fan diagram leads us to the conclusion that th e luminescence observed is due to transitions between electronic and hole s tates whose envelope wave functions are fully localized in the wells at the boundary of the superlattice (Tamm states).
