Self-organized Ge quantum wires on Si(111) substrates were grown by forming regular atomic steps followed by Ge deposition. Optical studies of the Ge wires suggest that these wires have a built-in biaxial strain equivalent to about 1% lattice mismatch. In addition, quantized optical transitions due to the confinement in Ge wire are also observed.
