# The single-layer/bilayer transition of electron systems in AlGaAs/GaAs/AlGaAs quantum wells subject to in-plane magnetic fields

@article{Smrcka1995TheST, title={The single-layer/bilayer transition of electron systems in AlGaAs/GaAs/AlGaAs quantum wells subject to in-plane magnetic fields}, author={L. Smrcka and Tom{\'a}{\vs} Jungwirth}, journal={Journal of Physics: Condensed Matter}, year={1995}, volume={7}, pages={3721-3732} }

Equilibrium properties of electrons in double-heterojunction AlGaAs/GaAs/AlGaAs structures are investigated theoretically, using a fully self-consistent numerical method. The transition from single to bilayer electron systems is discussed for structures with varying distance between interfaces as a function of the in-plane magnetic field strength. A phenomenon of separability of the energy dispersion curves in parts corresponding to electrons in either the first or the second layer is analysed…
