概要
- 論文の詳細を見る
We investigated the ultrafast optical responses of a one-dimensional (1D) Mott insulator by applying fs pump-probe absorption spectroscopy on a thin film sample of a Br-bridged Ni compound. Transient absorption changes and their excitation-energy dependences reveal that the responses consist of three components; coherent responses, responses of excitons and charge carriers. The decay time of excitons is very small (〜1.4ps), which is characteristic of 1D Mott insulators. The relatively slow relaxation of charge carriers with several tens of picoseconds is attributable to polaronic effects.
