# Analysis of electric-field-induced spin splitting in wide modulation-doped quantum wells

@article{Ekenberg2008AnalysisOE, title={Analysis of electric-field-induced spin splitting in wide modulation-doped quantum wells}, author={Ulf Ekenberg and Dejan M. Gvozdi{\'c}}, journal={Physical Review B}, year={2008}, volume={78}, pages={205317} }

We analyze the proper inclusion of electric-field-induced spin splittings in the framework of the envelope function approximation. We argue that the Rashba effect should be included in the form of a macroscopic potential as diagonal terms in a multiband approach rather than the commonly used Rashba term dependent on k and electric field. It is pointed out that the expectation value of the electric field in a subband is sometimes not unique because the expectation values can even have opposite…
