Allen, Leslie H. Zhang, Ming 2015-09-25T20:52:48Z 2015-09-25T20:52:48Z 10000-01-01 2003 2003 The silicide study focuses on phase formation in Au-Si thin films. The unique finding is to determine the melting temperature of metastable phase using calorimetry, which is ∼60°C below the eutectic melting point (363°C). The heat of fusion (26.4 kJ/mol) of the metastable phase has also been obtained. The metastable phase is analyzed to be an orthorhombic structure (a = 0.92, b = 0.72, c = 1.35 nm) by double tilting experiment with stereographic projection method (ex-situ TEM). The composition is proposed to be Au3Si from EDAX. The real-time experiment shows the melting point depression of eutectic and competitive growth between eutectic and Au3Si phase. The composition of the film (i.e., gold-rich or silicon-rich) determines the formed phase. Rapid cooling experiments reveal that eutectic is supercooled down to much lower temperatures (∼135°C) than the Au3Si phase (∼275°C). Made available in DSpace on 2015-09-25T20:52:48Z (GMT).
