Abstract
Semiconductor nanocrystals of size smaller than the exciton Bohr radius are interesting as prototypical systems for the physics of quantum confinement. To date, most studies have been limited to II-VI materials such as CdSe.1–4 Recent advances in the synthesis process now allow one to provide monodisperse samples of nanocrystals of the III-V material InP.5,6 We use femtosecond three pulse photon echo (3PPE) experiments1,2 and nanosecond transient hole-burning (HB) spectroscopy3,4 to investigate the electronic structure and dephasing dynamics in this novel material.
