Abstract

We present Hall mobility data μ(T) in the range T=300-600 K for GaInP₂, an alloy whose band gap has been shown to decrease with increasing compositional ordering. Samples grown to give high ordering are found to have consistently lower mobilities than samples with low ordering, suggesting that the mobility is limited by cluster scattering by ordered domains. We analyze μ(T) in terms of a cluster scattering model developed by Marsh [Appl. Phys. Lett. 41, 732 (1982)] and others to estimate the relative volume fraction of cluster scattering sites in the ordered and disordered material.
