defect-engineered silicon light-emitting diodes

We correlated electroluminescence of p-n junction silicon light-emitting diodes (Si LEDs) with boron implant-induced defects and found that {113} defects other than dislocation loops result in strong silicon light emissions. The electroluminescence of {113} defect engineered Si LEDs is twenty-five times higher than dislocation loop engineered Si LEDs. This finding, for the first time, is highly significant for monolithic Si nanophotonics.
