Abstract

1.278μm laser emission has been observed in a SOI structure which has been nanopatterned to contain an array of nanopores. The optical transition is identified to be associated with phononless recombination mediated by the bistable, carbon-related G center. The present work is focused on increasing the luminescence intensity from nanopatterned Si by increasing the number of G centers present in the material. The G center density is increased by increasing the concentration of substitutional atoms in the lattice prior to nanopatterning. To this end, solid-phase epitaxial regrowth of carbon-rich silicon is utilized in order to take advantage of the increased solid solubility of carbon in silicon at the interface between crystalline and amorphous solid silicon.
