Thermal activation of valley-orbit states of neutral magnesium in silicon
Rohan Abraham, Valentina Shuman, Leonid Portsel +7
Interstitial magnesium acts as a moderately deep double donor in silicon, and is relatively easily introduced by diffusion. Unlike the case of the chalcogen double donors, the bind…

A Mg-pair isoelectronic bound exciton identified by its isotopic fingerprint in Si
Rohan Abraham, Adam DeAbreu, Kevin Morse +9
We use the greatly improved optical linewidths provided by highly enriched Si to study a photoluminescence line near 1017 meV previously observed in the luminescence spectru…

Further investigations of the deep double donor magnesium in silicon
Rohan Abraham, Adam DeAbreu, Kevin Morse +9
The deep double donor levels of substitutional chalcogen impurities in silicon have unique optical properties which may enable a spin/photonic quantum technology. The interstitial…
