摘要
In this paper, a novel method has been presented to fabricate Ge-rich poly-SiGe thin films on glass by chemical vapor deposition at temperatures as low as 300 degrees C. The nucleation mechanism of Ge on insulator has been investigated and the crystal quality of poly-SiGe has been confirmed by Raman spectra, XRD and TEM analyses. The results indicate that the poly-SiGe thin films fabricated by this method are applicable for SiGe-based electronic and optical devices on inexpensive substrates. Moreover, fabrication of high quality poly-SiGe thin films on a-Si thin film enables the application in multi-junction solar cell as the bottom cell. (C) 2015 Acta Materialia Inc.
