We introduce Si/Ge self-assembled quantum dots for infrared applications operating in the 3-5 μm range. Conventional Si/Ge quantum well structures are transparent to such wavelengths in the absence of heavy doping. We show that the high degree of strain lowers the bandgap and also that the electrons and holes are both localized in the interracial region. This will consequently enhance the optical transition probabilities.
