中文摘要	a two-step approach of preparation for sige/si heterogeneous nanostructures, which combined with ultra-high vacuum chemical deposition and electrochemical anodization techniques, is demonstrated. uniformly distributed nanostructures with a quite uniform distribution of size and morphology are obtained. a strong room-temperature photoluminescence from the nanostructures was observed with a narrow full-width at half-maximum of around 110 mev. the possible origins of the two main peaks at around 1.6 and 1.8 ev have been discussed in detail. the two-step approach is proved to be a promising method to fabricate new si-based optoelectronic materials.
