Nearing the limit of Moore's Law?

Moore's Law describes how the number of transistors that can be cheaply placed on a computer chip doubles almost every two years. In 2005, Gordon Moore noted that transistors would eventually reach the limits of atomic levels and scientists working with nanotechnology have now created a transistor using apparently only seven atoms.

The "Quantum Dot" embedded in a single silicon crystal in the heart of the nanoscopic transistor measures only 4 nanometres across and promises a new generation of super computing.
