▪ Abstract Photoexcitation of a semiconductor with photons above the semiconductor band
gap creates electrons and holes that are out of equilibrium. The rates at which the …

We propose a new method of generating nonclassical optical field states. The method uses
a semiconductor device, which consists of a single quantum dot as active medium …

Low-dimensional semiconductor structures, often referred to as nanocrystals or quantum
dots, exhibit fascinating behavior and have a multitude of potential applications, especially …

The spectroscopic behavior of colloidal InP quantum dots (QDs) has been investigated as a
function of the mean QD diameter (which ranged from 26 to 60 Å). Absorption spectra show …

With the rapid development of technologies for the fabrication of, as well as applications of
low-dimensional structures, the demands on characterization techniques increase. Spatial …

Photoluminescence (PL) spectroscopy has been performed on a set of self‐assembled InSb,
GaSb, and AlSb quantum dot (QD) heterostructures grown on GaAs. Strong emission bands …

The photoluminescence from individual InP quantum dots embedded in a matrix of GaInP
has been studied. In addition to the ground state emission that consists of several peaks, we …

Strong optical anisotropy is observed in the photoluminescence (PL) bands of both the InP
self-assembled quantum dots and the Ga 0.5 In 0.5 P matrix. From the linearly polarized PL …

Thin layers of InSb, GaSb and AlSb were grown on GaAs (0 0 1) by molecular beam epitaxy
and characterized in situ with scanning tunneling microscopy. All three materials exhibit a …
