Controlling exciton decay dynamics in semiconducting single-walled carbon nanotubes by surface acoustic waves

► Exciton decay in carbon nanotubes is remotely controlled by surface acoustic waves. ► The electric fields associated with surface acoustic waves slow down exciton decay. ► The slowdown is caused by a decreased radiative rate due to a quadratic Stark effect. ► Remote-control could be of interest for device applications of carbon nanotubes.
