Abstract

Two Mn-related luminescence peaks have been observed in a series of nominally undoped Ga0.47In0.53As/Al0.48In0.52As multiple quantum wells (MQW) grown lattice-matched on InP substrates by molecular beam epitaxy. These two peaks correspond to on-center and on-edge impurity states, respectively. The origin of the Mn impurities is outdiffusion from the Fe-doped semiinsulating InP substrate into the epitaxial layer. The binding energy of Mn acceptors, determined to be 53±3 meV in bulk-like Ga0.47In0.53As, increases to 80±5 meV for the on-center Mn state in a 58 Å MQW. The strong well-width dependence of the binding energy is explained in terms of the unique behavior of the Mn impurity in III-V semiconductors. The Mn in Ga0.47In0.53As and Ga0.47In0.53As/Al0.48In0.52As MQWs behaves predominantly as a deep impurity.
