摘要：

Self-organized Ge quantum wires were grown on regular atomic steps formed along [(1) over bar 10] direction on Si(111) substrates by annealing at 870 degrees C in vacuum. The samples were then studied by atomic force microscopy, polarization-dependent Raman scattering, and low temperature photoluminescence spectroscopy. The results suggest that good quality Ge quantum wires were formed and clear quantum confinement-induced quantization in the wires was observed. (C) 1999 American Institute of Physics.
