摘要
The growth of erbium-doped InP and (Ga,In)(As,P) lattice-matched to InP has been carried out using LPE, incorporating several refinements designed to reduce the deleterious formation of the oxide and hydride of erbium which have been a feature of previous reports. The work did not reproducibly result in material capable of Er-related luminescence near 1.54-mu-m. It is concluded that erbium-rich particulate inclusions in the layers are the major source of the 1.54-mu-m emission previously reported from such LPE layers.
