摘要：

We report on growth and characterization of modulation doped CdTe/Cd1-yMgyTe quantum well structures. Well resolved Shubnikov-de Haas oscillations and quantum Hall effect have been observed. In the best CdTe/Cd1-yMgyTe structures the modulation doping enabled fabrication of a two-dimensional electron gas with mobility exceeding 10(5) cm(2)/V s. This is the highest mobility reported in wide-gap II-VI materials. (C) 1998 Elsevier Science B.V. All rights reserved.
