Silicon technology is the basis for the electronics industry that increasingly impacts on every aspect of our lives.  Progress in the technology is driven by the continuing ability to increase the speed, capacity and functionality of devices whilst decreasing their size, cost and power consumption.  By achieving this year on year, the reach of silicon technology continues to increase and encompass applications that would not previously have been imagined.

This talk will provide an update on some of the activities of the Warwick NanoSilicon Group within the field of silicon and germanium epitaxy.  It will discuss how we are able to construct materials with control at the atomic level, including introduction of strain to the crystal lattice by using atoms of different sizes.  Topics of discussion will include the World’s first strained germanium transistors, light modulation by stacks of quantum wells based on silicon and cooling electrons in the mK regime at the flick of a switch.
