Quantum dots could lead to faster computers
Canadian researchers have made a breakthrough that could lead to computers that are faster, use less energy and operate at cooler temperatures.
Scientists at the National Institute for Nanotechnology in Edmonton say they have come up with a new way to control electrons using ultra-tiny single-atom quantum dots.
The dots are composed of a single atom of silicon measuring less than one nanometre in diameter - that's one-billionth of a metre. Project leader Robert Wolkow said the research will be key to developing new forms of silicon-based electronic devices such as ultra-low power computers.
