Carbon Nanotubes: Quantum Dot–Carbon Nanotube Hybrid Phototransistor with an Enhanced Optical Stark Effect (Adv. Funct. Mater. 29/2013)
A simple and effective way to develop hybrid phototransistors with extraordinary optoelectronic properties is demonstrated by M. S. Jeong, Y. H. 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.
