Ultrafast asymmetric Rosen-Zener-like coherent phonon responses observed in silicon
Yohei Watanabe, Ken-ichi Hino, Nobuya Maeshima +2
We investigate the spectral profiles of time signals attributed to coherent phonon generation in an undoped Si crystal. Here, the retarded longitudinal-optical (LO) phonon Green fu…
Irregular Oscillatory-Patterns in the Early-Time Region of Coherent Phonon Generation in Silicon
Yohei Watanabe, Ken-ichi Hino, Muneaki Hase +1
Coherent phonon (CP) generation in an undoped Si crystal is theoretically investigated to shed light on unexplored quantum-mechanical effects in the early-time region immediately a…
Polaronic-Quasiparticle Picture for Generation Dynamics of Coherent Phonons in Semiconductors: Transient and Non-Linear Fano Resonance
Yohei Watanabe, Ken-ichi Hino, Muneaki Hase +1
We examine generation dynamics of coherent phonons (CPs) in both of polar and non-polar semiconductors -- such as GaAs and Si -- based on a polaronic-quasiparticle (PQ) model. In t…
