| Description | Journal: Japanese Journal of Applied Physics Time-resolved optically detected magnetic resonance (TR-ODMR) experiments have been performed on $Si/Si_{1- x }Ge_{ x }$ superlattices grown by molecular beam epitaxy (MBE) on (001) Si. These structures exhibit a single, broad (full width at half-maximum amplitude ∼70 meV) photoluminescence (PL) band with peak energy 100 meV below the expected band gap. Fast (τ≤5 µ s) and slow (τ≃20 µ s) processes have been separated with the TR-ODMR. The slow resonances are new and provide more detailed information on the nature of the recombination. These features are tentatively assigned to Ge-rich regions in the SiGe layers based on the resonance parameters and the faster spin-lattice relaxation. |
