ABSTRACT
Anomalous behavior in Hall data of molecular beam epitaxial In0.52Al0.48As/InP for T≥400 K suggests the presence of alloy clustering. The relaxation time for alloy clustering has been determined and analysis of measured data gives an estimate of composition fluctuation and cluster size. Evidence of clustering in the same samples is also obtained from the measured velocity-field characteristics, low-temperature photoluminescence data, and carrier impact ionization coefficients.
