Uva Virtual Lab: Quantum Dot Cellular Automata (Qca) Logic Gates

In computers of the future, transistors may be replaced by assemblies of quantum dots called "Quantum-dot Cellular Automata." This is a description of how QCA's can store and move information.

We have all seen Van de Graaff generators, but how does one work? It comes down to two fairly simple consequences of charge attraction and repulsion and a bit of treachery. Take a look at these video clips illustrating the Van de Graaff.

Scanning Probe Microscopes position their sensing tips to precisions better than 10-10 meters (the size of a single atom!). This incredible control is based on the use of "piezoelectric crystals." These materials bend or shrink in the...

This page describes the operation of Nanosurf Inc's "easyScan" atomic force microscope (AFM). Virtual reality is used to take apart the microscope and show how a laser controlled feedback loop allows the probe to measure the shape of a...
