Fascinating (and sometimes technologically important) phenomena occur in systems that
have a spatial dimension comparable to that of a fundamental physical, chemical, or …

This article presents a comprehensive review of recent progress of research dedicated to
low‐dimensional nanomaterials constructed from functional low‐molecular‐weight organic …

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

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 …

Quantum dots or rings are artificial nanometre-sized clusters that confine electrons in all
three directions. They can be fabricated in a semiconductor system by embedding an island …

In semiconductor heteroepitaxy the growing film frequently undergoes a series of strain relief
mechanisms that may include surface reconstruction, step bunching, faceting, and finally …

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 …

The self-organization of pyramidal PbSe islands that spontaneously form during strained-
layer epitaxial growth of PbSe/Pb1− x Eu x Te (x= 0.05 to 0.1) superlattices results in the …

Abstract Quantum dots,,,,,, or 'artificial atoms' are of fundamental and technological interest—
for example, quantum dots, may form the basis of new generations of lasers. The emission in …

This paper reports two fundamental observations on the size-dependent optical properties of
colloidal gold nanoparticles. First, faceted gold nanocrystals in the size range of 63±3 nm …
