The carrier transport in strain-induced laterally ordered (InP)2/(GaP)2 quantum wire (QWR) samples was examined with a noncontact Haynes-Shockley diffusion measurement which utilized time-resolved scanning cathodoluminescence. An anisotropy in ambipolar diffusion along the  and [11̄0] directions (perpendicular and parallel to the QWRs, respectively) was observed. The temperature dependence of this anisotropy was measured, revealing that carrier diffusion along the QWR direction is thermally activated.
