Abstract

We demonstrate that lightly-doped Si(P) displays extremely sharp absorption lines – the narrowest yet reported for any impurity in natural Si. The Zeeman splitting of many of these lines in magnetic fields <10 T has been studied previously by a number of groups. In this paper we focus on the behavior of metastable states associated with conduction-band Landau levels. The use of a rather heavily doped sample and strong magnetic fields, up to 18 T, assists in the observation of these.
