When is a metal not a metal? The ultrafast electron and phonon dynamics of Au246(SR)80 nanoclusters reveal that Au246 is still non-metallic despite its large size (2.2 nm in diameter). A prominent oscillatory feature with frequency of 0.5 THz is observed indicating the presence of a small band-gap and thus non-metallic or molecular-like behaviour.

2.2 nm Au246(SR)80纳米团簇的非金属性

什么时候金属不是金属?Au 246(SR)80纳米团簇的超快电子和声子动力学表明,Au 246尽管尺寸很大(直径为2.2 nm),但仍是非金属的。观察到频率为0.5 THz的突出振荡特征,表明存在小的带隙,因此存在非金属或类似分子的行为。
