First All-Gas Phase Manufacture of a Nanocrystal Based Electronic Device

Semiconductor nanocrystals hold great potential for the low-cost manufacture of electronic devices.  To date, nanocrystal-based devices have exclusively been produced from colloidal solutions, which requires solvents and added processing steps to add and remove them. IRG-4 and IRG-2 researchers demonstrated the first all-gas-phase manufacture of a silicon nanocrystal light-emitting device.  This study may establish a new paradigm for the solvent-free, “green” manufacture of nanocrystal-based electronics.
