摘要：

Far-infrared magnetotransmission and magnetophotoconductivity measurements on selectively doped GaAs-GaAlAs multiple-quantum-well structures reveal photoionization transitions from two-dimensional D- centers to successive Landau levels. Selective doping of the quantum-well structure favors the formation of D- centers in the well. The two-dimensional nature of this center results in a dramatic enhancement of its binding energy with respect to the three-dimensional case. © 1990 The American Physical Society.
