Quantum-dot Cellular Automata (QCA) - Memory Cells
03 Feb 2006 | Animations | Contributor(s): John C. Bean
Scientists and engineers are looking for completely different ways of storing and analyzing information. Quantum-dot Cellular Automata are one possible solution. In computers of the future, transistors may be replaced by assemblies of quantum dots called Quantum-dot Cellular Automata (QCAs).This …

Scanning Probe Microscope Piezoelectric Crystals
16 Nov 2005 | Animations | Contributor(s): John C. Bean
In this resource we disassemble the piezoelectric assembly of a scanning probe microscope. At its core is a white cylinder of the piezoelectric material. If you look closely, it has a granular texture that reflects the fact that it is actually made up of many small crystals.
