Femtosecond multidimentional spectroscopy to study carrier dynamics of photonic materials
conference contribution
posted on 2024-07-11, 11:51 authored by Lap Dao, My Thi Tra Do, Petrissa Eckle, Peter HannafordPeter Hannaford, Peter Reece, Mark Aizengendler, Alex StancoMultidimensional nonlinear coherence spectroscopy based on spectrally resolved femtosecond 2-colour 3-pulse photon echo measurements has been used to investigate the carrier dynamics and energy structure of porous silicon - an indirect band gap material. Short times are found for electron localization (~ 500 fs) and electron hopping (~ 3 ps), which are dependent on the porosity of the sample. A spin-orbit energy splitting for the conduction and valence band can be deduced.
