Pump fluence dependence of ultrafast carrier dynamics in InSb measured by optical pump-terahertz probe spectroscopy

Ultrafast carrier dynamics in intrinsic and n-doped InSb crystals were studied by time-resolved terahertz spectroscopy using an optical pump-terahertz probe setup with pump fluence from 32  μJ/cm to 1910  μJ/cm . With photoexcitation at 800 nm, the ultrafast photoinduced absorption and carrier recov...
