This book is a collection of some of the invited talks presented at the international
meeting held at the Max Planck Institut fiir Physik komplexer Systeme, Dresden,
Germany during August 6-30, 2001, on the rapidly developing field of nanoscale
science and bio-electronics (http://www.mpipks-dresden.mpg.de/~nanobio/).
Semiconductor physics has experienced unprecedented developments over the second
half of the twentieth century. The exponential growth in microelectronic processing
power and the size of dynamic memories has been achieved by significant downscahng
of the minimum feature size.

Magnetoluminescence from trion and biexciton in type-II quantum dot
Rin Okuyama*, Mikio Eto and Hiroyuki Hyuga
Abstract We theoretically investigate optical Aharonov-Bohm (AB) effects on trion and biexciton in the type-II semiconductor quantum dots, in which holes are localized near the center of the dot, and electrons are confined in a ring structure formed around the dot. Many-particle states are calculated numerically by the exact diagonalization method.
This book deals with theoretical and experimental aspects of solid-state lasers, including optimum waveguide design of end pumped and diode pumped lasers. Nonlinearity, including the nonlinear conversion, up frequency conversion and chirped pulse oscillators are discussed. Some new rare-earth-doped lasers, including double borate and halide crystals, and feedback in quantum dot semiconductor nanostructures are included.
Cd1-xMnxS nanoparticles (NPs) with size quantum confinement belong to the diluted
magnetic semiconductor (DMS) quantum dot (QD) class of materials that has been widely
studied in the last few years. The study of quasi-zero-dimensional Diluted Magnetic
Semiconductors (DMS), such as Cd1-xMnxS Quantum Dots (QDs), is strongly motivated due
to the localization of magnetic ions in the same places as the free-like electron and hole
carriers occurring in these nanomaterials [1,2].
There is growing concern about the safety of engineered nanoparticles,
which are produced for various industrial applications. Quantum dots are
colloidal semiconductor nanoparticles that have unique luminescence char-acteristics and the potential to become attractive tools for medical imaging.
However, some of these particles can cause oxidative stress and induce cell
