Phase Transition Induced Vertical Alignment of Ultrathin Gallium Phosphide Nanowire Arrays on Silicon by Chemical Beam Epitaxy
Vertical Alignment Ultrathin Gallium Phosphide Nanowire Arrays Silicon Chemical Beam Epitaxy
2016/12/2
CBE and CVD were performed in an ultra-high vacuum (UHV) system. The background pressure was kept at 1 × 10-10 mbar. The Au was deposited by MBE on a hydrogen terminated Si substrate with a surface te...
Fragmentation of Xe129 in the Liquid-Gas Phase Transition Region
Nuclear multifragmentation mass distribution symmetry energy surface energy excitation energy

我们利用Born-Mayer-Huggins相互作用势函数对(KF)N(N=108，256，500和864)团簇进行了分子动力学(MD)模拟。为了避免周期性边界条件对相变、成核和重结晶的干扰作用，对体系采用了自由边界。基于MD模拟结果，对团簇的熔化温度、熔化焓、扩散系数、成核速率、固液界面自由能、临界核大小等进行了计算和讨论。在对(KF)864双晶团簇的热退火模拟中，观察到了固态的重结晶和晶粒的生...
