Quantum Wells, Quantum Wire, and Quantum Dots




I'd like to explore the material known as Wellstone. There are some interesting aspects to this material, and it is written about in Hacking Matter by Will McCarthy. It is not necessarily nanotechnology, so much as it is quantum level materials and bio-molecular control over nano sized or meso-sized particles.
We will return to the world of Nanotechnology and DNA computing shortly, for now - let's talk about Wellstone.

Small-signal modelling of the transistor laser including the quantum capture
and escape lifetimes



The transistor laser was rst introduced in , and it was
predicted that this device could have a high-speed modula-
tion bandwidth of up to 100 GHz . In the transistor laser
(TL), a quantum well (QW) is embedded in the base of the
bipolar junction transistor (BJT) and acts as an optical col-
lector. The stimulated recombination causes compression in
the I- ....etc

The infrastructure of the Information Age has to date relied upon advances in microelectronics to produce integrated circuits that continually become smaller, better, and less expensive. The emergence of photonics, where light rather than electricity is manipulated, is posed to further advance the Information Age. Central to the photonic revolution is the development of miniature light sources such as the Quantum dots(QDs).

Definition

Quantum Dot Lasers can be considered as a quantum leap in the development of lasers. Quantum Dots improve basically the laser emissions. This property of Quantum Dots is well utilized for fiber optic communication, which is now the leading subject under research and development. Quantum Dots are thus very well used in applications fiber optic communication. The remaining major division of the field of quantum electronics deals with the interactions of coherent light with matter and again leads to a wide range of all-optical and op ....etc

Applications of Majority Gates with Quantum-Dot Cellular Automata(QCA)

Not much research was done on the circuits based on majority gates, as the incompatibilities in hardware donâ„¢t permit the CMOS technologies to do so. But this emerging computational nanotechnology called the quantum-dot cellular automata (QCA) has been a great help in learning more about the majority Gates, as it happens to be its primary logic primitive. Characterizing the three variable Boolean function to a simplified m ....etc

ABSTRACT
Quantum Dots(QDs) are small conductive regions in a semiconductor, containing a number of charge carriers(from one to thousand) that occupy well defined discrete quantum states. They have typical dimensions between nanometers to a few microns .When the space at any side, around a material shrinks to 100Ã…, quantisation of the energy levels at the reduced side will occur. In quantum dots electrons are confined in all directions to a volume in space with dimensions on the order of their de Broglie wave lengt ....etc
