在金属单壁碳纳米管中，通过低剂量中能Ar+辐照，实现了能级间隔高达200mev的盒内粒子态量子点。傅里叶变换扫描隧道光谱与法布里-珀罗电子谐振器模型的结果相比，产生了连续辐照诱导缺陷（缺陷间距离）之间的电子在通道间和通道内散射的清晰特征
Intratube quantum dots showing particle-in-a-box-like states with level spacings up to 200 meV are realized in metallic single-walled carbon nanotubes by means of low dose medium energy Ar+ irradiation. Fourier-transform scanning tunneling spectroscopy compared to results of a Fabry-Perot electron resonator model yields clear signatures for inter- and intravalley scattering of electrons confined between consecutive irradiation-induced defects (interdefects distance
