摘要：

Pb1-xEu(x)Se/PbSe multi-quantum-well (MQW) structures were grown by molecular beam epitaxy and their crystalline perfection was determined by X-ray diffraction measurements. Annealing experiments were performed in order to determine the Eu interdiffusion coefficient D. An upper bound of D = 4 x 10(-18) cm2/s at a substrate temperature of T(s) = 370-degrees-C was found from X-ray diffraction as well as from secondary ion mass spectroscopy (SIMS) measurements. This small interdiffusion coefficient offers excellent prospects for the growth of single and mulitquantumwell lasers in this material system.
