Split Dirac cones in HgTe/CdTe quantum wells due to symmetry-enforced level anticrossing at interfaces
S. A. Tarasenko, M. V. Durnev, M. O. Nestoklon +3
We describe the fine structure of Dirac states in HgTe/CdHgTe quantum wells of critical and close-to-critical thickness and demonstrate the formation of an anticrossing gap between…
Charge tuning in [111] grown GaAs droplet quantum dots
L. Bouet, M. Vidal, T. Mano +10
We demonstrate charge tuning in strain free GaAs/AlGaAs quantum dots (QDs) grown by droplet epitaxy on a GaAs(111)A substrate. Application of a bias voltage allows the controlled c…
Excited states of exciton-polariton condensates in 2D and 1D harmonic traps
C. Trallero-Giner, M. V. Durnev, Y. Núñez Fernández +3
We present a theoretical description of Bogolyubov-type excitations of exciton-polariton Bose-Einstein condensates (BECs) in semiconductor microcavities. For a typical two dimensio…
Magneto-Photoluminescence of InAs/InGaAs/InAlAs quantum well structures
Ya. V. Terent'ev, S. N. Danilov, J. Loher +8
Photoluminescence (PL) and highly circularly-polarized magneto-PL (up to 50% at 6 T) from two-step bandgap InAs/InGaAs/InAlAs quantum wells (QWs) are studied. Bright PL is observed…
