Population dynamics and dephasing of excitons and electron-hole pairs in polytype wurtzite/zinc-blende InP nanowires
We investigated the dephasing and population dynamics of electron-hole (e-h) pairs and excitons in vapor-liquid-solid grown polytype wurtzite/zinc-blende (WZ/ZB) InP nanowires (NWs) using heterodyne four-wave mixing (HFWM) in three-beam configuration at temperatures from 80 to 270 K. The photon energy of the 100 fs excitation pulses was varied to predominantly excite either mobile excitons and e-h pairs or indirect WZ/ZB excitons. The population dynamics reveal a multiexponential decay with...[Show more]
