Au-hyperdoped Si produced by ion implantation and pulsed laser melting exhibits sub-band-gap absorption
in the near infrared, a property that is interesting for Si photonics. However, the sub-band-gap
absorption has previously been shown to be thermally metastable. In this work, we study the atomistic
processes that occur during the thermal relaxation of Au-hyperdoped Si. We show that the first step in
thermal relaxation is the release of substitutional Au from lattice sites. This process...[Show more]
