摘要：

The effective g-factor of modulation doped n-type HgTe single quantum wells, SQWs, has been determined by the coincidence method in tilted magnetic fields to lie between 15 and 35. For symmetrically doped samples the effective g-factor has been found to be constant for different filling factors; however, for asymmetric SQWs, a large increase with increasing filling factor has been observed. This can be ascribed to a combination of Zeeman spin splitting and Rashba spin-orbit splitting. Reasonable agreement has been achieved between theoretical calculations based on the 8 x 8 k (.) p method and experimental results. (C) 2004 Elsevier Ltd. All rights reserved.
