We present the first findings of a study of infrared-induced emission
from silicon quantum wires, which is due to the formation of a correla
tion gap in the DOS of the degenerate hole gas. The quantum wires in t
his case are created by an electrostatic confining potential inside ul
tra-shallow p-n junctions which are realized using controlled surface
injection of self-interstitials and vacancies in the process of non-eq
uilibrium boron diffusion. (C) 1998 Academic Press Limited.
