Fine structure of the energy levels of an exciton bound on a boron atom in silicon
Karasyuk V. A., Pokrovskii Ya. E.
The fine structure of the phononless emission line of an exciton bound on a boron atom in silicon, with and without compression along the (111) axis, is investigated. An interpretation is proposed for this structure that takes into account the valley-orbital splitting, j-j pairing of holes, and electron-hole exchange interaction.
