中文摘要
正电子寿命谱表明,在杯状碳纳米管(CNTs)中有正电子素原子形成,而在多壁碳纳米管(MNT)中没有。通过符合多普勒展宽谱,解释了由石墨烯片和石墨边缘平面组成的碳纳米管锯齿形表面上的正电子湮没。
英文摘要
It was demonstrated by positron-lifetime spectroscopy that positronium atoms are formed in cup-stacked carbon nanotubes (CNTs) but they are not found in multi-walled carbon nanotubes (MNTs). The difference is explained in terms of positron annihilation on zigzag surfaces of CNTs, which are composed of both graphene-sheet and graphite-edge planes, by coincidence Doppler broadening spectroscopy.
