A diverse printed future

摘要

An approach that entails printing compound-semiconductor ribbons on a silicon substrate offers the means to build nanoscale transistors that can be switched on and off much more effectively than their bulk analogues. rnFor applications in electronics, silicon is often referred to as 'God's material'. Characteristics such as high natural abundance, and relative ease in crystal growth, purification and doping, combine with favourable electronic-transport properties to provide unmatched capabilities for commercial integrated circuits.
