Quantum communication relies on the availability of light pulses with strong quantum
correlations among photons. An example of such an optical source is a single-photon pulse …

We present an overview of the theoretical background and experimental re sults in the
rapidly developing field of semiconductor quantum dots-systems 8 6 of dimensions as small …

The initial stages of GaAs overgrowth over self-assembled coherently strained InAs quantum
dots (QDs) are studied. For small GaAs coverages (below 5 nm), atomic force microscopy …

Nanoscale science and technology is a young and burgeoning field that encompasses
nearly every discipline of science and engineering. With rapid advances in areas such as …

Visible-stimulated emission in a semiconductor quantum dot (QD) laser structure has been
demonstrated. Red-emitting, self-assembled QDs of highly strained InAlAs have been grown …

Self-assembled InAs quantum dots (QDs) embedded in GaN 0.007 As 0.993 strain
compensating layers have been grown by metalorganic-molecular-beam epitaxy on a GaAs …

Thermal generation rate in quantum dots (QD) can be significantly smaller than in quantum
wells, rendering a much improved signal to noise ratio. QDs infrared photodetectors were …

Carrier relaxation in self-organized In 0.4 Ga 0.6 A s/G a A s quantum dots is investigated by
time-resolved differential transmission measurements. The dots have a base dimension of …

We apply low temperature confocal optical microscopy to spatially resolve, and
spectroscopically study, a single self-assembled quantum dot. By comparing the emission …

Chemical doping of organic semiconductors has been recognized as an effective way to
enhance the electrical conductivity. In perovskite solar cells (PSCs), various types of dopants …
