Transient Terahertz Conductivity of GaAs Nanowires

Parkinson, Patrick Wallace; Lloyd-Hughes, J; Gao, Qiang; Jagadish, Chennupati; Johnston, Michael B; Herz, Laura; Tan, Hark Hoe


The time-resolved conductivity of isolated GaAs nanowires is investigated by optical-pump terahertz-probe time-domain spectroscopy. The electronic response exhibits a pronounced surface plasmon mode that forms within 300 fs before decaying within 10 ps as a result of charge trapping at the nanowire surface. The mobility is extracted using the Drude model for a plasmon and found to be remarkably high, being roughly one-third of that typical for bulk GaAs at room temperature.
