چکیده

We report the results of time-integrated and time-resolved photoluminescence spectroscopy on red-emitting self-organized InAs/Al0.6 Ga0.4As quantum dots with indirect barriers. Spatially resolved PL measurements confirm that carriers excited in the Al0.6Ga0.4As barriers are consistent with a carrier hopping process between dots, a result also supported by time-resolved PL experiments. q 2003 Elsevier Science Ltd.

Spin effects in InAs self-assembled quantum dots

We have studied the polarized resolved photoluminescence in an n-type resonant tunneling diode (RTD) of GaAs/AlGaAs which incorporates a layer of InAs self-assembled quantum dots (QDs) in the center of a GaAs quantum well (QW). We have observed that the QD circular polarization degree depends on applied voltage and light intensity. Our results are explained in terms of the tunneling of minority...

Photoluminescence measurements of quantum-dot-containing semiconductor microdisk resonators using optical fiber taper waveguides

Optical fiber taper waveguides are used to improve the efficiency of room temperature photoluminescence measurements of AlGaAs microdisk resonant cavities with embedded self-assembled InAs quantum dots. As a near-field collection optic, the fiber taper improves the collection efficiency from microdisk lasers by a factor of 15–100 times in comparison to conventional normal incidence free-space c...

Size distribution effects on self-assembled InAs quantum dots

We report on the unusual behaviors of the optical properties for self-assembled InAs/GaAs quantum dots (QDs) by using photoluminescence (PL) spectroscopy. Distinctive double-emission QD peaks are observed in the PL spectra of the samples grown on high growth-temperature condition. From the excitation power-dependent and temperature-dependent PL measurements, these doubleemission peaks are assoc...

Photoluminescence characteristics of InAs self-assembled quantum dots in InGaAs/GaAs quantum well

Three different InAs quantum dots QDs in an InGaAs/GaAs quantum well were formed and investigated by time-resolved and temperature dependent photoluminescence PL . A strong PL signal emitting at 1.3 m can be obtained at room temperature with a full width at half maximum of only 28 meV. Dots-in-a-well structures result in strong stress release and large size InAs QDs which lead to narrowing and ...

The Influence of a Continuum Background on Carrier Relaxation in InAs/InGaAs Quantum Dot

We have investigated the ultra-fast carrier dynamics in Molecular Beam Epitaxy (MBE)-grown InAs/ InGaAs/GaAs quantum dots (QDs) emitting at 1.3 lm by time resolved photoluminescence (TRPL) upconversion measurements with a time resolution of about 200 fs. Changing the detection energies in the spectral region from the energy of the quantum dots excitonic transition up to the barrier layer absorp...
