Silicon’s inability to produce light efficiently has been stymying attempts to develop optical devices from the microelectronics industry’s favourite element. Fabricating the material in a nanocrystalline form could help but many promising applications – such as waveguides, CMOS chips and non-volatile memories – are not compatible with the high temperatures used to produce silicon nanocrystals. Now researchers at McGill University in Canada have demonstrated a cooler one-step approach………..
