Terahertz magneto-optical spectroscopy of two-dimensional hole and electron systems
N. Kamaraju, W. Pan, U. Ekenberg +6
We have used terahertz (THz) magneto-optical spectroscopy to investigate the cyclotron resonance in high mobility two-dimensional electron and hole systems. Our experiments reveal…
Analysis of electric-field-induced spin splitting in wide modulation-doped quantum wells
U. Ekenberg, D. M. Gvozdic
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 include…
Realization of efficient electroabsorption using intersubband transitions in step quantum wells
P. Holmström, P. Jänes, U. Ekenberg +1
We have demonstrated efficient intersubband electroabsorption in InGaAs/InAlGaAs/InAlAs step quantum wells grown by metal-organic vapor phase epitaxy (MOVPE). An absorption modulat…
Efficient switching of Rashba spin splitting in wide modulation-doped quantum wells
D. M. Gvozdic, U. Ekenberg
We demonstrate that the size of the electric-field-induced Rashba spin splitting in an 80 nm wide modulation-doped InGaSb quantum well can depend strongly on the spatial variation…
Superefficient electric-field-induced spin splitting in strained p-type quantum wells
D. M. Gvozdic, U. Ekenberg
We investigate theoretically the efficiency of the Rashba effect, i.e. the spin splitting resulting from an electric field. This is the mechanism behind the Datta-Das spin transist…
