With this in mind, optical pump-terahertz probe (OPTP) spectroscopy is ideally suited to studies of nanowires: it provides non-contact measurement of carrier transport and dynamics at room temperature. OPTP spectroscopy has been used to assess key electrical properties, including carrier lifetime and carrier mobility, of GaAs, InAs and InP nanowires. The measurements revealed that InAs nanowires exhibited the highest mobilities and InP nanowires exhibited the lowest surface recombination velocity. © 2013 Copyright SPIE.GaAs | III-V nanowires | InAs | InP | mobility | Semiconductor nanowires | surface recombination velocity | terahertz spectroscopyconference paper10.1117/12.20490162-s2.0-84894127661https://api.elsevier.com/content/abstract/scopus_id/84894127661
