英文摘要	Nation Natural Science Foundation of China [61176050, 61036003, 61176092, 60837001]; National Basic Research Program of China [2012CB933503]; Fundamental Research Funds for the Central Universities [2010121056]; We present the systematic investigations of the microcavity effects from SiGe/Si heterogeneous nanorods (HNRs) prepared by electrochemical anodization of SiGe/Si multiple quantum wells. Visible photoluminescence (PL) emission with narrow bandwidth is observed because of the wavelength selective effect of the microcavity. The resonance of the microcavity is confirmed by the temperature dependent PL measurement, which is consistent with the prediction from the thermo-optic effect. Furthermore, electroluminescence from the ITO/i-SiGe/Si HNR/n(-)-Si diode shows multiple peak emissions under low current density, which is in good agreement with the PL results.
