description: Research of quantum levels filling in single InP/GaInP QD have been described in the master's thesis. Relaxation and recombination times for different states and lateral size quantizationâs value are defined by this. The tasks deciding in this work are present below:
1. Study of fillings process, Stark effect and phenomenon of Coulomb blockade in quantum dot;
2. Registration and analysis of microphotoluminescence spectra of single QD at different optical capacity in the helium cryostat;
3. Registration of photon emission curve for different electron states by timeresolved spectroscopy;
4. Modeling and analysis of microluminescence dynamic with rate equations using;
5. Registration and analysis of microphotoluminescence spectra of single QD at different electric bias.
Zero-dimensional systems assembly is explored in most existing work on photoluminescence of QDs. Separate quantum levels filling
is next to almost impossible to watch in this case. Measurements is carried out with microphotoluminescence methods using in given work. Electronic properties of InP/GaInP structure are investigated under the action of optical pumping and electric bias. Filling of high-energy state is observed in both cases. The value of quantum retention can be found in virtue of this. Quantum Stark
effect is also demonstrated in spectrum. Measurements and modeling of PL dynamics offer the possibility to spot the relaxation and recombination times for all states.
