Nanotechnology: How clean is too clean?
Ulrich Gösele1
Abstract
Silicon nanowires could form the building-blocks of future electronic devices, but under ultra-clean conditions, regulating their growth is difficult. Is the strictly controlled environment the problem?
At the heart of the success of microelectronic gadgets, from laptop computers to mobile phones and iPods, is the fact that silicon-based electronic devices keep getting smaller. In the most advanced of such devices currently in production, the smallest features that regulate the flow of current are less than 100 nanometres in size.
