Core/shell-structured CdSe/CdS nanoparticles were prepared by a one-pot procedure. The
interface effect was studied by steady-state and time-resolved photoluminescence …

We report on the deterministic fabrication of sub-μm mesa-structures containing single
quantum dots (QDs) by in situ electron-beam lithography. The fabrication method is based …

Few‐particle effects of zero‐dimensional charge carriers in self‐organized quantum dots
(QDs) are investigated both experimentally and theoretically. The actual three‐dimensional …

We studied the optical properties of wurtzite III-N heterostructures by means of various
photoluminescence methods. Polarization resolved photoluminescence experiments …

Since the discovery of the photocatalytic splitting of water on TiO 2 electrode by Fujishima
and Honda in 1972, enormous effort has been spent on the study of TiO 2 under light …

We have observed and investigated random telegraph noise in the photoluminescence (PL)
from small InP quantum dots (QDs) in GaInP. Very few of the QDs exhibit switching between …

The goal of this thesis was to investigate light-matter interaction in nanophotonic devices
based on site-controlled pyramidal quantum dots (QD) in photonic crystal (PhC) cavities …

Quantum dots (QDs), also known as semiconductor nanocrystals, are fluorescent
nanoparticles with unique, size-tunable optoelectronic properties. QDs form an active field of …

A single photon is among the few quantum mechanical systems that are finding applications
in myriad fields. The applications include serving as building blocks for the ongoing …

We report the growth and characterisation of CdSe quantum dots grown by MBE with Zn0.
2Mg0. 8S0. 64Se0. 36 barriers and their subsequent characterisation by 77K PL and 4Kμ …
