MS Jeong， YH Lee及其同事展示了一种简单有效的方法来开发具有非凡光电性能的混合光电晶体管。在第3653页，他们用半导体量子点装饰单壁碳纳米管（SWCNT）表面。这种混合结构表现出明显的负光响应和光开关行为，可以通过施加外部栅极偏置进一步调谐。此外，这种混合结构在不施加任何外部电场的情况下显示出“光学斯塔克效应”的增强。
A simple and effective way to develop hybrid phototransistors with extraordinary optoelectronic properties is demonstrated by MS Jeong, YH Lee and co-workers. On page 3653, they decorate singlewalled carbon nanotube (SWCNT) surfaces with semiconducting quantum dots. This hybrid structure shows a clear negative photoresponse and optical switching behavior, which could be further tuned by applying an external gate bias. Moreover, this hybrid structure shows an enhancement in the ‘optical Stark effect’without applying any external electric field.
