摘要:

价带光电子发射与周围的Mn2p激发阈值的光子能量已被用来研究纳米线的MnAs颗粒催化的发展。随着纳米线长度的增加,光谱逐渐变化,这样的共振光电发射最终占主导地位的俄歇衰变通道。这种变化归因于Mn的稀释,表明Mn从MnAs颗粒转移到纳米线中。

英文摘要:

Valence band photoemission with photon energies around the Mn2p excitation threshold has been used to study the development of nanowires catalyzed by MnAs particles. A gradual change in the spectra with increasing nanowire length is observed, such that the resonant photoemission eventually dominates over the Auger decay channel. The change is ascribed to dilution of Mn, showing that Mn is transferred from the MnAs particles into the nanowires.
