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.

INTRODUCTION
The history of computer technology has involved a sequence of changes ~ZT\ one type of physical realization to another from gears to relays to valves to ~3nsistors to integrated circuits and so on. Today's advanced lithographic *r-:hniques can squeeze fraction of micron wide logic gates and wires onto the s^face of silicon chips. Soon they will yield even smaller parts and inevitably ¦each a point where logic gates are so small that they are made out of only a -^ndful of atoms; i.e. the size of the lo ....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

Quantum Mirage

ABSTRACT
Since it first appeared on the cover of Nature in February 2000, the quantum mirage” has featured on posters, calendars, websites and the covers of various books and magazines. The image – which was obtained using a scanning tunnelling microscope – shows the electronic wavefunctions inside an elliptical “quantum corral” made of cobalt atoms on a copper surface. It was created by Hari Manoharan, Christopher Lutz and Don Eigler of the IBM Almaden Research Center in California. In 19 ....etc

Quantum Mirage


INTRODUCTION
1.1 OVERVIEW
Today, an MP3 player that is smaller than a book of matchbox can hold four gigabytes of information – enough space to store about 750 to 1000 songs. When it comes to the capabilities, power, speed and energy efficiency that are capable of being packed into a cell phone or a laptop, a phenomenon called quantum mirage portends that the surface may have only been scratched so far. Essentially ....etc

Imagine a computer whose memory is exponentially larger than its apparent physical size; a computer that can manipulate an exponential set of inputs simultaneously; a computer that computes in the twilight zone of Hilbert space. You would be thinking of a quantum computer. Relatively few and simple concepts from quantum mechanics are needed to make quantum computers a possibility. The subtlety has been in learning to manipulate these concepts. Is such a computer an inevitability or will it is too difficult to build?
