Quantum confined Stark effect in quantum wires: Wave function splitting and cascading

We show that the two-dimensional quantum confined Stark effect in a semiconductor quantum wire can display novel behaviour, i.e. wave function splitting and cascading. No analog to these phenomena can be found in bulk material or quantum wells. The consequ ...

Quantum confined Stark effect due to built-in internal polarization fields in (Al,Ga)N/GaN quantum wells

Nicolas Grandjean

(Al,Ga)N/GaN quantum wells have been studied by temperature-dependent luminescence and reflectivity. The samples were grown by molecular beam epitaxy on (0001) sapphire substrates, and well widths were varied from 3 to 15 monolayers (ML's) with a 2-ML incr ...

Optical properties of ultrathin GaAs layers embedded in AlxGa1-xAs

We present a comparison between the predictions of two theoretical models and experimental results on ultrathin GaAs layers with a thickness in the range from 1 to 8 ML embedded in bulk (AlxGa1-x)As, 0.30 less than or equal to x less than or equal to 0.34. ...

Optical stark effect and coherent gain of excitons in a semiconductor microcavity

Romuald Houdré, Ursula Oesterle

We report transient sub-picosecond pump and probe experiments performed on a semiconductor microcavity into which quantum wells have been inserted. The cavity is featuring resonance and strong coupling with the exciton. It is strongly and resonantly excite ...

Magnetooptical Studies of Acceptors Confined in Gaas/Alxga1-Xas Quantum-Wells

Alfredo Pasquarello

A magneto-optical study of accepters in varying degrees of confinement in GaAs/Al-x Ga-l-x, As quantum wells (QW's) is presented. A model for the splitting of the acceptor bound exciton (BE) and the allowed BE transitions in the presence of a magnetic fiel ...
