摘要：
The composition dependence of the nucleation free energy barrier W* in amorphous Si-1. Ge-x(x) thin films is investigated. Within the composition range of x = 0.25 similar to 0.52, the nucleation free energy barrier exhibits a maximum, which is in a good agreement with our theoretical analysis. The results are significant for processing polycrystalline SiGe thin films with desirable microstructures for thin film transistor applications. In addition, the incubation time of crystallization of amorphous Si1-xGex (x=0.5) thin films is investigated as a function of temperature.
