| 摘 要： | 用Stillinger-Weber势计算了Sin(N=2—7)小颗粒的基态几何结构及基态能量。由Keating模型描述原子间的弹性能,计算了这些结构的振动谱。并从物态方程出发,估计了小颗粒Si的熔化温度,发现Si4和Si6的熔化温度相对较高。

| Abstract: | The ground-state structures and ground-state energies of small Sin (N = 2-7) clusters are investegated using the Stillinger-Weber potential. The vibrational spectra of these structures are calculated with the elastic energy discribed by Keating model. Form the equation of state, the anelting temperatures are estimated. The melting temperatures of Si4 and Si6 are relatively high. |
